Glenn Dorsey might not be ready to play for several more months, but the 49ers feel he’s worth signing for a couple more years.
The team Tuesday signed the nose tackle, who was destined for free agency 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. The 49ers planned to start him this season, and they 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.
Biceps tears generally require four months to heal. 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.”
Dorsey was drafted fifth overall by Kansas City in 2008. He signed a two-year deal with the 49ers last offseason and started 13 games, finishing with two sacks on a defense that finished fourth in rushing yards allowed per game (95.9). Dorsey was selected by his coaches and teammates as the 49ers’ “Defensive Blue Collar Player of the Year.”
With Dorsey out for at least the beginning of the season, the 49ers hope Ian Williams can regain his form from last offseason, when he won the starting spot at nose tackle. Williams suffered a broken ankle and ligament damage in Week 2 and resumed practicing only last week.
He didn’t play in Sunday’s exhibition loss to Denver, but there’s a good chance the 49ers’ presumed starting defensive line – Justin Smith, Ray McDonald and Williams – will be on hand Sunday against San Diego.
Davis said he likely would miss the remaining exhibition games – Sunday vs. the Chargers and Aug. 28 at Houston – but added he doesn’t need the preseason to be ready for Week 1.
If coaches and the team’s medical staff don’t think he’ll be ready by the Sept. 7 opener at Dallas, the starting right tackle job would go to Jonathan Martin, who received good grades for his work Sunday. While Martin played right and left tackle against Baltimore on Aug. 7, all 32 of his snaps against Denver were from the right side.
“Jonathan Martin has done very well,” coach Jim Harbaugh said. “He’s been a great addition to our football team. Sure glad we got him. Like everybody on our football team, he’s working to improve in certain areas. But he has been very effective and efficient at what he’s doing.”
