(UPDATE: Carlos Rogers was on a side field doing rehab work at the start of today’s practice. It appears he won’t participate in practice).

Two days after a report stated Carlos Rogers was not expected to play in Sunday’s wild-card game at Green Bay, 49ers defensive coordinator Vic Fangio suggested the cornerback had a chance to start at Lambeau Field.

Rogers didn’t practice Wednesday, but Fangio said Rogers’ prognosis has brightened. He’ll attempt to practice the next two days and see how his hamstring responds. On Tuesday, the National Football Post reported Rogers was not expected to play against the Packers.

“It’s yet to be determined,” Fangio said of Rogers’ playing status. “I think he’s going to give it a shot today. The injury is not as bad as originally feared. We’ll see how he does today and tomorrow.”

If Rogers can’t play, the 49ers will start Tramaine Brock and Tarell Brown outside and Eric Wright will serve as the No. 3 cornerback and cover the slot. If such a scenario unfolds, Wright figures to see plenty of action. In a season-opening 34-28 win against Green Bay, Nnamdi Asoumgha, then the 49ers’ No. 3 cornerback, played 57 of 62 defensive snaps.

Rogers, the 49ers’ slot cornerback, has played in 53 straight games, including the playoffs, since signing with San Francisco in 2011. Wright has played 120 snaps in six games with the 49ers, but has started 81 career games and has extensive experience covering the slot. Wright covered the slot on 41 percent of his 1,277 defensive snaps from 2010 to 2012, according to Pro Football Focus.

Despite his more-optimistic outlook regarding Rogers’ injury, it sounds as if Fangio is preparing for Wright to assume the nickel role Sunday.

“I hope he’s well prepared, but the answer to that will come on Sunday, for sure,” Fangio said. “He hasn’t played a lot of nickel for us … Carlos has been our nickel here for ever how many games we’ve played here, so this will be our first game without him as our nickel. So we’ll find out on Sunday.”
