Davis’ status unclear

San Francisco right tackle Anthony Davis was able to drive home following a cross-country flight from New York last month despite feeling “loopy” from a concussion he didn’t initially realize was so severe. He said he took an elbow to the head during the Nov. 16 victory over the Giants. Davis hasn’t played in two games since, and leaves a void on the 49ers offensive line. His status for Sunday’s game at Oakland is unclear as Davis hasn’t practiced, but he did lift weights and do cardio work Wednesday. Davis experienced a “white fog” in the days after the head injury. A first-round draft pick in 2010 out of Rutgers, he started every game his first four seasons. Davis tweeted that Coach Jim Harbaugh hollered for get him off the field after the injury.

The Tennessee Titans already have lost one starting wide receiver this week because of a lacerated spleen. Now another starter has a sore right hand that kept him out of practice Thursday. Coach

Ken Whisenhunt said Kendall Wright hurt his hand on a route Wednesday, so the Titans gave him the day off to rest his hand. Wright wore a splint on his hand during the open portion of practice. The Titans placed Justin Hunter on injured reserve Tuesday, and Wright is their leading receiver with 51 catches for a team-best five touchdowns. Their backups include

Derek Hagan with eight catches and Kris Durham who has yet to play. Whisenhunt said they should know more about Wright’s hand today and his availability for Sunday’s game with the New York Giants.
