Midway through the third quarter of the Kansas City Chiefs playoff game with the Cleveland Browns on Sunday, Chiefs quarterback Patrick Mahomes took a hard hit, leaving the field to undergo concussion protocol.

Enter backup quarterback Chad Henne.

Henne threw his first post-season pass, which was promptly batted down at the line. He finished the drive 1-of-2 for five yards passing, leading to a Chiefs field goal that expanded the Kansas City lead to 12.

The Chiefs had a bye last week, but the week prior Henne was named the starter for the final game of the regular season against the Los Angeles Chargers, giving Mahomes a rest.

It was the first time since September of 2014 that Henne, a former Michigan quarterback, had stepped on the field as a starter in the NFL. He would end the game by completing 23-of-32 passes for 218 yards and two touchdowns in the Chiefs’ 38-21 loss.

Shortly after the beginning of the fourth quarter, the CBS broadcast confirmed Mahomes has a concussion and will not return, leaving Henne to complete the game. If Henne is able to secure the win, it will be interesting to see how Mahomes progresses heading into the AFC Championship Game.

Should Mahomes not clear concussion protocol, Henne would likely be in line to start with a shot at the Super Bowl.
