Anthony Davis makes health strides


SANTA CLARA, Calif. -- The incremental injury news was positive Thursday for the San Francisco 49ers.

Right tackle Anthony Davis (shoulder) practiced on a limited basis after sitting out Wednesday. That is a good sign he will be able to play Sunday against Houston. The Texans have blitzed more than any team in the NFL this season. Thus, Davis’ role will be vital.

Star inside linebacker Patrick Willis (groin), tight end Vernon Davis (hamstring) and No. 3 cornerback Nnamdi Asomugha (knee) all were limited Thursday for the second straight day. Barring setbacks, all three players have a strong chance to play against the Texans.

“I think Pat’s getting a lot better, making great progress,” San Francisco defensive coordinator Vic Fangio said Thursday. “I think the chances are better than 50-50, but we don’t know for sure yet.”
