49ers hope NT Dorsey returns this season

SANTA CLARA, Calif -- The San Francisco 49ers are holding out hope that nose tackle Glenn Dorsey, who underwent surgery to repair a torn left biceps on Aug. 4, will return this season.

In fact, while the injury was initially feared season-ending, Dorsey could be a candidate for the Injured Reserve/Designated To Return list, which would mean he would have to sit out the 49ers’ first eight games.

“When [the doctors] got in there, they felt like it could not have gone better,” coach Jim Harbaugh said Friday. “There was no frayed [tissue]. It was good. It was a real good surgery.

“So that was the talk going in: Would he be back in 3 ½ months? Would it be four? Would it be longer? And all indications that I’ve gotten, it looks like a 3 ½-month [recovery].”

Dorsey was awarded this week with a two-year extension through 2016 worth nearly $11 million.

If Dorsey’s timetable for recovery is indeed 3 ½ months, that brings him back in late November. So as long as the 49ers don’t want to use the IR/Designated to Return label on someone else, Dorsey would be the one to wear that tag and not count against the 53-man roster.

“We’d like it to happen, yeah we would,” Harbaugh said. “As an orginzation, we’d like to see that happen.”

Mike Purcell has started at nose tackle in each of the 49ers’ first two exhibition games.
