Kevin Kolb's injury history stays in focus

CANTON, Ohio -- The rib contusion Kevin Kolb suffered in the Hall of Fame Game on Sunday night was the latest injury setback for the Arizona Cardinals' potential starting quarterback.

It's not yet clear if Kolb will miss an extended period. The injury did knock him from the game against New Orleans, inviting a quick review of the oft-injured quarterback's medical file.

Kolb missed four starts last season after suffering a toe injury against Baltimore in Week 8. He missed the final three games of the season after suffering a concussion against San Francisco in Week 14.

With Philadelphia in 2010, Kolb suffered a concussion in Week 1 against Green Bay, missing two-plus games.

In 2009, also with the Eagles, a knee injury sidelined Kolb for the first two exhibition games.

Some injuries are unavoidable or close to it. Others can be avoided if a quarterback gets rid of the ball quickly.

It's tough to know initially if Kolb held the ball too long Sunday night. Kolb was running away from New Orleans' Sedrick Ellis when he threw a hurried pass to fullback Anthony Sherman for a 4-yard gain. Ellis caught Kolb and landed on him.

Kolb completed 1 of 4 passes for 4 yards and an interception.
