With leading receiver Michael Crabtree sidelined at least until November due to a torn Achilles tendon all signs point toward tight end Vernon Davis becoming a primary target for quarterback Colin Kaepernick.

Perhaps that's why Davis has spent some of training camp lining up at wide receiver. His speed and athleticism make him a matchup nightmare for opposing defensive coordinators and it makes sense for the 49ers to get creative in finding ways to get him the ball.

"I'm willing to step up and do whatever they ask me to do" Davis said Sunday. "They've been having me line up at wide receiver pretty much all over the place. It's a good thing that I get the opportunity to work with those guys because it not only helps me at the wide receiver position it also helps me at the tight end position. My feet get quicker my route-running is better."

If playing out of position on occasion is what it takes to get the 49ers over the hump to win a Super Bowl Davis says he's all for it. He took inspiration from Atlanta Falcons star tight end Tony Gonzalez's decision to postpone retirement and come back for another season at age 37.

"This is a guy who has nothing to prove" Davis said. "He's already (deserving) of the Hall of Fame he's broken all the records. This tells me how important it is to him to get a ring.

"I don't play for the Pro Bowl I don't play for statistics. Maybe in my younger days I played for statistics. It's all about that ring."

Davis said he played some receiver in high school and hoped to play there once he got to the University of Maryland but his head coach said "You'll be too big" Davis remembers.
