TEMPE, Ariz. -- Arizona Cardinals tight end Stephen Spach will miss the rest of the playoffs with a torn knee ligament.

Spach tore his right anterior cruciate ligament while blocking in the second half of the Cardinals' 33-13 victory over Carolina on Saturday night.

Spach was signed as a free agent on Oct. 28 to shore up the injury-depleted position and became a starter against San Francisco on Nov. 10.

His blocking helped the team's improved running game, and he had a clinching 23-yard catch on a third-and-16 situation late in Arizona's 30-24 wild-card victory over Atlanta.
