On Sunday, Steelers quarterback Ben Roethlisberger suffered a knee injury after taking a low hit from Rams safety Mark Barron. Barron wasn’t flagged on the play, and he reportedly won’t be fined.

Per Ed Werder of ESPN, the league office isn’t expected to fine Barron for the low hit.

Dirty or not, the hit from Barron violates the rules. From Rule 12, Section 2, Article 9(e): “A rushing defender is prohibited from forcibly hitting in the knee area or below a passer who has one or both feet on the ground, even if the initial contact is above the knee. It is not a foul if the defender is blocked (or fouled) into the passer and has no opportunity to avoid him.”

So it should have been a foul. And since we often see personal fouls result in fines, why wouldn’t a personal foul that tears up a quarterback’s knee result in a fine?
