That ugly knee injury suffered by Steelers rookie linebacker Sean Spence has generated an understandably serious initial diagnosis.

Per a source with knowledge of the situation, Spence is believed to have a torn ACL, torn LCL, and dislocated kneecap.

Spence, a third-round pick from Miami, undoubtedly is headed to injured reserve.  Hopefully, it’s an injury from which he’ll be able to recover in time for the 2013 season.
