Source: Steelers fear DE Tuitt tore biceps

The Pittsburgh Steelers fear defensive end Stephon Tuitt suffered a torn biceps Sunday, a source told ESPN’s Adam Schefter.
If an MRI that, according to sources, is scheduled Monday confirms that the biceps is torn, Tuitt would miss the season.
Stephon Tuitt was given a five-year extension, making the Steelers the only NFL team with two DEs in a 3-4 scheme with contracts in excess of $50 million.
Tuitt signed an extension Saturday that is part of a new six-year deal. Sources told Schefter that deal is worth $61 million.
Tuitt, a second-round pick in 2014, has 108 tackles and 11.5 sacks in three seasons and added a tackler in Sunday’s win over the Browns.
