Steelers LT Kelvin Beachum suffers torn ACL

Steelers left tackle Kelvin Beachum will miss the remainder of the season with a torn ACL, Pittsburgh coach Mike Tomlin told reporters.

Beachum suffered the injury in the second quarter of Sunday's 25-13 win over the Arizona Cardinals. He went down awkwardly after a Cardinals player fell into Beachum's leg while he was blocking another player. 

Beachum, a seventh-round pick out of SMU, is playing in the final year of his rookie contract, one that he has outplayed as a starter the last two-plus seasons.

Former Army Ranger Alejandro Villanueva replaced Beachum at left tackle.
