BOISE, Idaho (AP) - Richie Brockel, the starting tight end and captain of the No. 6 Boise State offense, is expected to miss the rest of the season with a foot injury.

Brockel, who has eight catches for 75 yards and two touchdowns this season, injured his left foot in the Broncos' 63-25 blowout over rival Idaho Saturday. Coach Chris Petersen declined to provide details of the injury, but said Brockel, a senior, is undergoing tests Monday.

Petersen and teammates said Brockel's value is in setting the physical tone for the offense and being a leader.

The Broncos (10-0) also lost freshman running back Matt Kaiserman for the season. Kaiserman, who saw his first action last month at Hawaii, suffered a broken right leg. In four games, Kaiserman has 33 carries for 150 yards and one touchdown.
