Matt Maiocco, of the Santa Rosa Press Democrat, reports San Francisco 49ers TE Delanie Walker will play as the team's No. 3 tight end during the Week 5 game.

WR Taylor Jacobs (hamstring) practiced Thursday, Oct. 5 and is questionable for the Week 5 game.

OG Larry Allen (knee) participated in part of practice Thursday, Oct. 5 but did not work in team drills. He is listed as doubtful for the Week 5 game and appears unlikely to play.

TE Vernon Davis (leg) missed practice Thursday, Oct. 5 and is out for Week 5.
