SANTA CLARA, Calif. – Strong safety Antoine Bethea, who suffered a concussion last Sunday, practiced Friday while wearing the noncontact blue jersey over his uniform, seemingly confirming San Francisco 49ers coach Jim Harbaugh’s take from earlier in the day.

“I think that’s likely that he would be cleared to play Sunday,” Harbaugh said. “But I don’t think we’re going to play him on Sunday.”

The 49ers play host to the San Diego Chargers at Levi's Stadium in each team’s third exhibition game. Bethea suffered a concussion in the second quarter of the 49ers’ 34-0 loss to the Denver Broncos.

Bethea came to the 49ers as a free agent after eight seasons and two Pro Bowl appearances with the Indianapolis Colts.

In other injury news, right tackle Anthony Davis suited up fully for practice for the first time since undergoing offseason shoulder surgery. He told reporters earlier this week that he did not have to play in an exhibition game to be ready for the 49ers’ season opener Sept. 7 at the Dallas Cowboys. Davis has not missed a game in his four-year career.

Also, linebacker Patrick Willis (stinger) was still wearing the blue jersey, as was nose tackle Mike Purcell (unknown).

Receiver Michael Crabtree was back after being in Texas for the birth of his son Michael III on Monday.
