SANTA CLARA -- Glenn Dorsey may not be ready to play for several more months, but the 49ers feel he's worth signing for a couple more years. The team on Tuesday signed Dorsey, a nose tackle who was scheduled to become a free agent in March, to a two-year contract extension.
Dorsey, 29, tore his left biceps tendon during practice Aug. 1 and had surgery three days later. He had been earmarked as the starting nose tackle this season, and the 49ers are weighing whether to place him on injured reserve with a designation to return, which would allow him to come back in the second half of the season.
Bicep tears generally are four-month injuries. The 49ers must decide on the designation – only one is allowed per team – by Sept. 2.
“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.”
With Dorsey out for the beginning of the season at least, the 49ers are hoping that Ian Williams can regain the form he had last offseason when he won the starting spot at nose tackle. Williams suffered a broken ankle and ligament damage in Week 2, and he only began practicing again last week.
He didn't play in the recent preseason loss to Denver but there's a good chance the 49ers' starting defensive line – Justin Smith, Ray McDonald and Williams – will be on hand Sunday against the Chargers.
Dorsey started 13 games last season, finishing with two sacks on a defense that finished fourth in rushing yards allowed per game (95.9). He also was selected by his coaches and teammates as the 49ers’ ‘Defensive Blue Collar Player of the Year.’ The fifth overall draft pick by the Chiefs in 2008, Dorsey signed a two-year deal with the 49ers last offseason.
