With No. 22 Iowa State hosting Baylor Saturday afternoon, things got heated between the conference foes. 

Early in the third quarter after a run by Cyclones running back David Montgomery, a fracas broke out away from the ball. Players rushed over to break things up including Montgomery and Bears defensive lineman Greg Roberts. Montgomery pulled Roberts off the pile and away from the action, and that didn't seem to sit well with the 6-foot-5, 264-pounder. 

The incident came one play after Baylor safety Chris Miller was assessed a 15-yard penalty for a late hit out of bounds on Montgomery. On that play, Stewart didn't let up when the two ran out of bounds and pushed Montgomery into the Gatorade cart. Pushing and shoving ensued, and referees had to break it up.

Roberts and Montgomery were ejected for fighting, and Montgomery is suspended for the first half of Iowa State's Week 12 game at Texas pending any appeals. He finished Saturday's game with 53 yards rushing on 11 carries to go along with 25 yards receiving on three catches. Following the game, Montgomery took to Twitter to apologize for the incident.

"First I would like to apologize to Cyclone nation and my team for my actions," Montgomery wrote, "Me as a captain should have not reacted the way I did and I sincerely apologize for that! But I will defend my brothers no matter what and I stand on that!"
