Injured nose tackle Glenn Dorsey's future became a little more secure Tuesday.
The San Francisco 49ers announced they have signed the nose tackle to a two-year extension through 2016. He was set to become a free agent next spring.
"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 in a statement. "He is a quick study and a very good football player that has earned this extension, and we look forward to his future contributions."
Dorsey sustained a torn biceps tendon in his left arm Aug. 1 early on in training camp. He has since been replaced by Ian Williams, who is coming off four surgeries to repair a broken ankle suffered in Week 2 of last season.
Last year, Dorsey's first with San Francisco after joining the team as a free agent from Kansas City, Williams broke camp as the starter before being replaced by Dorsey following the injury.
Dorsey went on to have a very good year in Williams' absence, earning Pro Football Focus' 10th-highest grade against the run among nose tackles. He was a key contributor to the league's fifth-ranked run defense. Dorsey had two sacks and 41 tackles, according to their metrics.
Dorsey remains on the roster and looks like a candidate to be placed on injured reserve with the designation to return. If he receives that designation, he must miss at least the team's first 11 games.
