49ers will try to extend Michael Crabtree, Mike Iupati

San Francisco 49ers general manager Trent Baalke said he will try to re-sign wide receiver Michael Crabtree and offensive guard Mike Iupati before they hit the free-agent market. 

Baalke says he doesn't want negotiations to become a distraction from football, but at the same time he realizes both players are in the final season of their contract. 

"We're going to try," Baalke said, via CSN Bay Area. “We're going to work at it, certainly. But at some point, you got to stop negotiating deals and let these guys concentrate on playing football. I don't know what point that is. We'll make that determination as a club.”

Crabtree, who signed a six-year, $32 million contract in 2009, played only five games last season after recovering from a torn Achilles tendon. He had 19 catches for 284 yards and one touchdown.

Iupati, on the last season of a five-year, $15 million deal, has started all 60 games he has appeared in since the team selected him in the first round of the 2010 NFL draft. 

"But we're certainly going to work toward that goal,” Baalke said. “Those are two very good football players, and guys we'd love to have in this organization for the long term."
