Kolb to have MRI after X-Rays come back negative
Reporter: Jason Barr; Sports Director
TUCSON (AP) Embattled Arizona quarterback Kevin Kolb took one hit too many, and it's uncertain whether he will be able to return to lead the Cardinals against the Vikings at Minnesota next Sunday.
Kolb injured his ribs while being sacked for the fifth time in Sunday's wild 19-16 overtime loss to Buffalo. Coach Ken Whisenhunt says X-rays were negative for anything broken but an MRI was planned to make sure.
John Skelton, active for the first time since spraining his left ankle in the season opener, relieved Kolb and threw a key pass to Larry Fitzgerald to set up the ill-fated 38-yard field goal try that would have won the game for Arizona as regulation ended.
