Jonas Jennings is back at practice this week, but to hear Mike Singletary tell it, the right tackle job is Adam Snyder's to lose. "Right now, he has to earn that," Singletary said of the possibility of Jennings regaining his starting job. "Snyder is working his tail off. ... Right now Snyder's the guy."
Jennings, of course, dislocated his shoulder almost nine weeks ago against Seattle. He returned to practice in a limited fashion last week and has been full go this week. Still, trainers and coaches are being cautious. Jennings suffered shoulder dislocations in 2005 and 2006.
Asked whether Jennings is healthy enough to start, Singletary said, "We really won't know until we need him. To me right now, the more he's out, the better. It gives him time to get stronger."
The 49ers, meanwhile, wanted to give Snyder, their so-called swing tackle in previous seasons, a permanent position this year. They placed him at left guard in the offseason, but he struggled there in the summer and was recently replaced by David Baas. Snyder has said he's always felt most comfortable at tackle - that's where he played in college, after all - and he had a particularly good game Monday against the Cardinals. Asked if he was impressed with how Snyder played, Singletary said, "I was. I really was. I was impressed with the entire offensive line."
Singletary said Frank Gore moved well in practice and should be fine for Sunday. He said that Mark Roman "showed a lot of promise" as far as his groin injury and the coach is optimistic he will play at free safety. He said Roman would be a game-time decision. If he can't play, Keith Lewis would start. Singletary wasn't as optimistic about tight end Delanie Walker.
