SANTA CLARA, Calif. - The San Francisco 49ers have signed injured defensive lineman Glenn Dorsey to a two-year contract extension through the 2016 season. Dorsey, 29, is sidelined with a torn left biceps muscle that required surgery. He was injured Aug. 1, but hasnt been ruled out for the season. He is expected to miss significant time after arriving for training camp as the projected starting nose tackle. The 49ers announced the deal Tuesday afternoon, a few hours after coach Jim Harbaughs news conference. Dorsey is entering his seventh NFL season out of LSU. In 16 games with 13 starts last season in his first year with the Niners, Dorsey had 41 tackles and two sacks. By San Franciscos own count, his 100 tackles were a career high. "Glenn is a true pro who has quickly become a valued contributor to our organization both on and off the field," general manager Trent Baalke said. "He is a quick study and a very good football player that has earned this extension, and we look forward to his future contributions." Losing Dorsey was a devastating blow 11 months after 2013 starting nose tackle Ian Williams went down with a season-ending ankle injury in a Week 2 loss at Seattle. Dorsey quickly emerged as a reliable replacement and stabilizing force for the defensive line. Williams is making significant progress now that he has been activated from the physically unable to perform list. "Obviously, very disappointed for Glenn and him personally," defensive co-ordinator Vic Fangio said after the injury. "He was in great shape. Played great for us last year. Got better and better for us as the season went on last year and was looking even better this year. I feel bad for him. I feel bad for us that we wont have him for a while. Well just move on and get the rest of the guys ready." Dorsey joins a long list of players on the teams vaunted defence who will be around for the coming seasons, including star linebackers Patrick Willis, NaVorro Bowman and Ahmad Brooks.

Unger and Miller were both listed as probable on Fridays injury report. Unger has a pectoral injury that limited him earlier in the week. Miller missed two days of practice with a rib injury. Also probable are Richard Sherman (foot), Marshawn Lynch (shoulder) and Doug Baldwin (neck). Only Brandon Browner (groin), K.J. Wright (foot) and Harvin were ruled out. "All of the guys were out there that we were taking care of. Everyone made it back today," Seahawks coach Pete Carroll said after practice. Carroll said that Harvin has been unable to overcome the lingering soreness in his hip following his season debut in Week 11 against Minnessota.dddddddddddd Harvin worked to get back following hip surgery in August, but has been unable to get back on the field since. Harvin had one reception and had a long kickoff return the only two times he touched the ball in his one Seahawks appearance. "Its looking like its going to be a bit before we get it right. Hes doing a ton of stuff to get back, but he hasnt just turned the corner. Were going to just keep taking the time it takes to get him right," Carroll said. The team has said there is nothing structurally wrong, but Carroll said the fact Harvin has not been cleared to return to practice means hes still vulnerable. "Were going to make sure that we take our time and see when that time comes," Carroll said. "We still have a number of games left, hopefully. If we can get him in there, well take him when he comes."
