Detroit Lions linebacker DeAndre Levy wasn't fined for his low hit Monday night on Ravens quarterback Joe Flacco, according to a league spokesman.

Levy wasn't penalized for the hit, which happened during the fourth quarter of the Ravens' 18-16 win at Ford Field. Flacco sprained the medial collateral ligament in his left knee on the play.

The Ravens spoke to the league office about the hit earlier this week, sending the play in to be reviewed for potential discipline. Flacco was shaken up on Monday, but remained in the game and is set to play Sunday against the New England Patriots while wearing a brace on his knee.

“It should have been a penalty,” Ravens strong safety James Ihedigbo said Wednesday. “For the refs to miss something so blatant like that, it’s unacceptable. If a quarterback gets hit below the knee, that’s what the rule is there for.”

Meanwhile, Ravens free safety Matt Elam was fined $7,875 for unnecessary roughness. Elam was flagged for a personal foul in the  first quarter when he "unnecessarily struck the quarterback who slid feet first," according to the NFL.

Ravens outside linebacker Courtney Upshaw was fined $7,875 for an unnecessary roughness penalty he drew in the fourth quarter following Elam's interception.
