Alonso received a 15-yard penalty for the hit, but was not ejected.

Flacco was replaced by Ryan Mallett, who threw a touchdown on his first drive that targeted Alonso in coverage.

Following the play, a skirmish broke out, during which Alonso and Ravens head coach John Harbaugh engaged in a face-to-face screaming match.
