Dorsey may have escaped serious injury

SANTA CLARA, Calif. -- The diagnosis of San Francisco 49ers nose tackle Glenn Dorsey's right hamstring injury may be good.

San Francisco defensive coordinator Vic Fangio told radio station KNBR, “We don't think [the injury] is as bad as initially feared." Fangio added the 49ers will not know Dorsey’s status for Sunday’s game until later in the week.

Dorsey said Sunday he thought he’d be OK. He left the game in the first quarter after he suffered the injury. Dorsey later jogged on the sideline and left the field without a major limp.

Dorsey, a free-agent pickup from Kansas City, has been fantastic since taking over for Ian Williams, who was lost for the season in Week 2 with a leg injury. The 49ers are thin on the defensive line. Thus, it will be huge news for the team if Dorsey avoids missing extended time.

If I had to guess, I’d think the 49ers will be cautious with Dorsey this week and make a game-time decision in Nashville on Sunday.

In another 49ers note:

The Seahawks worked out former 49ers linebackers Larry Grant and Tavares Gooden. Pete Carroll never tires of looking at former 49ers. And, of course, Jim Harbaugh feels the same way about former Seahawks.
