Kansas City wide receiver Dwayne Bowe will miss the Chiefs' upcoming game against the Oakland Raiders with a rib injury.
Coach Romeo Crennel made the announcement during his Monday press conference, adding, "I don't know about the rest of the year yet."
The six-year pro is set to have an MRI on Monday to determine if he will need to be placed on injured reserve.
Bowe suffered the injury during Sunday's loss to the Cleveland Browns, which he finished with 70 yards on two receptions.
The former Pro Bowler leads the Chiefs with 801 yards and three touchdowns on 59 receptions through 13 games this season.
