WATCH: Nick Saban Breaks Headset After Penalties Force Alabama to Settle for Field Goal

Despite the Crimson Tide leading 28–10, Nick Saban broke his headset in frustration when a drive stalled.

Even as Alabama dominated the first half of Saturday's College Football Playoff semifinal against Oklahoma, Nick Saban didn't appear to be  satisfied.

With less than a minute remaining in the first half and Crimson Tide ahead 28–10, the Alabama head coach's frustration reached its limit. After three costly penalties that stalled a drive, Saban ripped his headset off and slammed it to the ground.

The Crimson Tide were inside the Sooners' red zone with 1:21 left when Jedrick Wills Jr. committed a false start penalty with Alabama facing third-and-one. On the ensuing play, Wills was flagged again, this time for illegal formation, pushing the Crimson Tide back into a third-and-10.

Alabama quarterback Tua Tagovailoa rushed for nine yards to set up a fourth-and-one chance with 29 seconds left in the half. But when the Crimson Tide lined up to go for it, Damien Harris commited a false start, setting Saban off.

"Our last offensive possession, we got three penalties and killed ourselves," Saban told ESPN's Maria Taylor as the teams broke for halftime.

Although Saban was frustrated, Alabama led Oklahoma 31–10 heading into halftime, with 30 minutes separating the Crimson Tide from their fourth straight national championship appearance.

Arizona State coach Herm Edwards, who joined ESPN's Coaches Film Room broadcast for the Orange Bowl, even accurately predicted Saban would break his headset.

"This is one of those headset things where you break your headset, right?" Edwards asked moments before Saban ripped his headset off.
