San Francisco 49ers

49ers light at tight end for Wednesday’s practice

The 49ers began practice today with just one healthy tight end from their 53-man roster, Derek Carrier. The other two, Vernon Davis (ankle) and Vance McDonald (knee), were working out in the team’s weight room. Davis emerged using the same crutches he was seen using after Sunday’s loss to the Bears.

Earlier in the day, Jim Harbaugh said the team “dodged a bullet” with Davis’ injury, which occurred when he was tackled awkwardly from behind in the fourth quarter. Still, it’s unknown whether the team’s top tight end will be ready in time for Sunday’s game against Arizona. He has a deep bruise on his ankle, a source said.

Meanwhile, cornerback Tramaine Brock (toe) and tackle Anthony Davis (hamstring) continue to rehabilitate from their injuries. If they cannot play, Perrish Cox and Jonathan Martin would continue to start in their place. In addition, Joe Staley, Justin Smith and Tank Carradine were not on the field when practice started. Carradine, who played five snaps in his first ever regular-season game Sunday, does not have a serious injury.

Neither Smith nor Staley seems injured and both could be getting so-called “veteran days” away from practice. Smith did not practice last Wednesday, either.
