NASHVILLE, Tenn. - Titans rookie quarterback Zach Mettenberger is doubtful against the New York Jets after aggravating his sprained right shoulder, but coach Ken Whisenhunt says there is a legitimate chance Mettenberger plays for Tennessee again this season.Whisenhunt said Monday that hes hopeful Mettenberger will be back this year and the rookie will be on a week to week basis with three games left this season.Im not going to rule him out until I know for sure that he cant go, Whisenhunt said. I said that he was doubtful he would go this week. But well see as it progresses.Seeing how the rookie responds is key for a franchise that needs to see if Mettenberger can be their starter in 2015. Mettenberger originally sprained his shoulder Nov. 30 in a loss at Houston, but he started Sunday against the New York Giants. He hurt his shoulder again at 10:41 of the fourth quarter when sacked for the fifth time in a 36-7 loss.Whisenhunt said he wasnt happy Mettenberger aggravated the injury. The coach also said he should have done a better job not letting that happen in a game where the Titans played without three starting offensive linemen and were down to a tackle signed Tuesday because of injuries.Going forward I think we are going to be conservative with it to a certain degree, but I think also its important that he stays in it and tries to get back, Whisenhunt said of Mettenberger. Thats an important piece of it. I mean theres a legitimate chance he plays again for us this year. If he has that and hes healthy, we would like to see that no question.Jake Locker is expected to start at quarterback if Mettenberger is out. The veteran in the final year of his contract was benched in October coming off an injured hand with Mettenberger starting the last six games.Its an opportunity to play, Jake wants that, Whisenhunt said. Prepare it the best he can and do the best job he can. I think thats the way hell look at it. Hes a good pro.Mettenberger was limited in practice all last week with his original sprained shoulder, and returning could be difficult. The Titans (2-11) host the Jets (2-11) on Sunday, then have a short turnaround before visiting Jacksonville (2-11) on Dec. 18.That leaves the season finale hosting Indianapolis (9-4) on Dec. 28 for a team already with 10 players on injured reserve, including six starters. But Whisenhunt said he hopes left tackle Taylor Lewan and right tackle Michael Oher, who have missed two straight games with injuries, could return. Oher is getting his sore left toe checked again Tuesday.Whisenhunt said Mettenberger, who had an MRI exam earlier Monday, was pretty sore.I know he wants to get back and play, Whisenhunt said. Well see as it goes.Notes: S Michael Griffin was using crutches in the locker room Monday for a sore back he hurt on the opening drive of the game. But Griffin said he will play against the Jets and former teammate Chris Johnson. CB Blidi Wreh-Wilson, who dislocated his left shoulder against the Giants, was wearing a sling Monday. S Daimion Stafford is in the concussion protocol.___Online:AP NFL website: www.pro32.ap.org and www.twitter.com/AP_NFL___Follow Teresa M. Walker at www.twitter.com/teresamwalkerDuncan Keith Jersey .

Tony Esposito Jersey . PETERSBURG, Fla. PRETORIA, South Africa -- Oscar Pistorius refused to look at a photo of his dead girlfriends bloody head wounds while testifying at his murder trial Wednesday as the prosecutor urged the star athlete to "take responsibility" for killing her. "Its time that you look at it," chief prosecutor Gerrie Nel said, setting the stage for a rigorous first day of cross-examination of Pistorius, the double-amputee Olympian charged with premeditated murder for shooting Reeva Steenkamp three times through a toilet door at his home. "I remember," Pistorius said of Steenkamps bloodied head, becoming distraught and then crying as he turned away from the gruesome image of the injuries he inflicted that were displayed next to him in a packed courtroom in South Africas capital. Nel said Steenkamps head "exploded" when it was struck by one of four hollow-point bullets that Pistorius fired through the door on Feb. 14, 2013 with his 9 mm pistol. The showing of the photograph on TV screens in the courtroom caused gasps among spectators, who included Steenkamps mother, June. The police photo showed a side view of the dead model and reality TV stars head, with a mass of blood and human tissue on the back and upper parts. Her eyes were closed. "I will not look at a picture where Im tormented by what I saw and felt that night," Pistorius said. "As I picked Reeva up, my fingers touched her head. I remember. I dont have to look at a picture, I was there." Pistorius, 27, says he shot Steenkamp in the pre-dawn hours on Valentines Day -- in the head, arm and hip -- by mistake thinking she was a dangerous intruder behind the door in his bathroom about to come out and attack him. Prosecutors charge he killed the 29-year-old intentionally, and Nel aggressively questioned Pistorius for the first time. "You killed her," Nel said. "You shot and killed her," and he asked Pistorius to say it. Pistorius would not, saying merely: "I did." Pistorius faces a possible prison term of 25 years to life if convicted of premeditated murder. Nel also showed a video, first broadcast by Sky News days before the trial started, of the celebrated athlete firing a gun at a watermelon at a shooting range. On the video, Pistorius can be heard saying the melon was "softer than brains" after it explodes when the bullet hits it, and calling the powerful .50-calibre handgun he was using a "zombie stopper." Referring to tthe watermelon, Nel said to Pistorius: "You know the same happened to Reevas head.dddddddddddd It exploded." Defence lawyer Barry Roux objected to the gun video being shown, saying it was inadmissible character evidence and amounted to a legal "ambush" of the defence. After the dramatic start, prosecutor Nel also started to poke holes in details of Pistorius version of the events of the fatal night. The champion runner said that his claim in a court document a year ago that he went out onto a balcony at his home before the shooting was incorrect. Pistorius said he went to the edge of the balcony but not outside. The discrepancy could be significant because Pistorius says he heard a noise in the bathroom that alerted him to a possible intruder, which would have been harder if he was out on the balcony. Nel tried to pin down Pistorius on whether he meant to fire into the toilet cubicle door at a perceived intruder, or whether his gun discharged accidentally. Pistorius said he didnt intend to shoot "anyone" and that he fired "before thinking" because he thought his life was in danger, prompting Nel to accuse him of weighing the legal implications of the question before answering. The dogged prosecutor implied that Pistorius, who grew more agitated, was becoming emotional because he was faced with a difficult question. The judge noted that Pistorius had been emotional throughout the trial. Pistorius told his questioner that he was trying to be careful with his answers because the stakes were high. "My life is on the line," he said. Nel retorted: "Reeva doesnt have a life anymore because of what youve done." And Nel tried to dismantle a sympathetic image of Pistorius that the defence had sought to build up in three days of testimony, asking the athlete to explicitly acknowledge that he killed Steenkamp. "I made a mistake," Pistorius said. "What was your mistake?" Nel shot back. Pistorius then said he "took Reevas life." Nel also questioned the defences portrayal of Pistorius as a good role model. The prosecution depicts him as an angry hothead with a gun obsession. The prosecutor asked Pistorius if people looked up to him as a sporting hero, if he would hide anything and if he lived by Christian principles. "Im here to tell the truth, Im here to tell the truth as much as I can remember," Pistorius said. He also said: "Im human. I have sins." ' ' '
