Watch: Steelers' Jason Worilds slaps Ravens' Crockett Gillmore

Pittsburgh Steelers linebacker Jason Worilds slapped Baltimore Ravens tight end Crockett Gillmore in Saturday's AFC Wild Card playoff game, but wasn't ejected.

Pittsburgh Steelers linebacker Jason Worilds slapped Baltimore Ravens tight end Crockett Gillmore in Saturday's AFC wild-card playoff game, but wasn't ejected.

That play occurred in the second quarter, after the Ravens' Justin Forsett gained eight yards on a rushing play. Worilds was flagged for a 15-yard unnecessary roughness penalty, but not ejected.

Throwing a punch will get a player ejected from a game, but as former NFL vice president of officiating and current FOX rules analyst Mike Pereira said, the rule differs for open-hand strikes.

No ejection for an open hand blow to the face. That is specific in the rule. Closed fist blow is to be an ejection. That was open hand.

The penalty gave the Ravens a first-and-10 at the Steelers' 30-yard line. The Ravens ended the drive with a 28-yard field goal by Justin Tucker to go up 10-6.
