Pittsburgh Steelers linebacker James Harrison has left the Sunday night game against the Baltimore Ravens with a right leg/knee injury.
Harrison already had a sack in the game and another pressure that resulted in an interception by linebacker Jason Worilds.
Harrison returned a few plays later.
Harrison had his first two sacks of the season last Sunday in the Steelers win over the Indianapolis Colts.
The Steelers currently lead the Ravens 14-7 in the second quarter.
