SANTA CLARA -- Veteran nose tackle Glenn Dorsey is back on the 49ers’ 53-man roster, but defensive coordinator Vic Fangio is not sure Dorsey will be back on the field Sunday against Washington at Levi's Stadium.
Dorsey has not experienced any setbacks since his return to practice after undergoing surgery on Aug. 4 to repair a torn left biceps. But Dorsey has not made significant progress since coming back to the practice field. And he was not on the practice field at the start of the 49ers' practice on Thursday.
“(He’s) about the same,” Fangio said Thursday. “I think Glenn’s at a point, where he’s kind of stuck. I don’t think he’s taken any steps backward. Nothing negative has happened. (He) just hasn’t taken that next step to where he feels he can go out and cut it loose, yet.
“It’s kind of where he was last week at this time. Medically, he’s healthy enough to play. He doesn’t have that little extra ‘oomph,’ that final ‘oomph’ that you need to go out there and play.
“Until he gets that, we won’t play him.”
The 49ers placed nose tackle Ian Williams on season-ending injured reserve this week with a fractured left fibula, which he sustained in the Nov. 9 game against the New Orleans Saints. Quinton Dial started at nose tackle for the 49ers on Sunday against the New York Giants.
