Baltimore Ravens head coach John Harbaugh has admitted that he was "disappointed" with the pass interference call against his side which led to a winning score for the San Diego Chargers in their NFL clash.

Anthony Levine was called for the penalty against Keenan Allen, which allowed the Chargers to move to the goal line and set up the winning touchdown for the visitors as Eddie Royal secured the victory for his side.

Harbaugh told reporters: "My understanding is both players - the offensive and defensive players - are supposed to have an opportunity to make a play on the ball.

"I saw a corner trying to make a play on the ball with a forearm in his chest and clavicle area being held down, not allowed to jump for the ball.

"That's disappointing in that situation. I think a corner should be given a chance to defend. I know he wasn't given a chance to defend on that play. That's not fair to the player."

The Ravens are 7-5 in their season following their defeat to the Chargers.
