Pittsburgh Steelers linebacker James Harrison has been ruled out for Sunday's game against the Tennessee Titans.

James Harrison is a four-time Pro Bowler and was named the 2008 AP Defensive Player of the Year.  The Pittsburgh Steelers will be without his services this Sunday.  Harrison will undergo a surgical procedure Wednesday for a broken orbital bone around his right eye.  Harrison suffered the injury during a 17-10 loss last Sunday against the Houston Texans.

Harrison might miss much more time than just this Sunday.  The outside linebacker is out indefinitely with no timetable for his return.  Steelers head coach Mike Tomlin commented that it was needless to say that Harrison will be out for a number of weeks.

Harrison posted an interesting comment on his Twitter page.  "I told y'all it's wasn't a concussion!! Lol I'll be ok in time."  I really never pegged the intense James Harrison for an "Lol" guy.  The Steelers face the (3-1) Titans this week.  Their next two games are against the (1-3) Jaguars and Cardinals.
