Dallas Cowboys defensive end DeMarcus Ware has not missed a game since entering the NFL in 2005 but that streak could be in jeopardy in Week 7 against the Philadelphia Eagles.

According to a source Ware and running back DeMarco Murray most likely will be unable to play against the Eagles because of injuries suffered in the team's 31-16 win Sunday against the Washington Redskins.

At 3-3 Dallas and Philadelphia share the lead in the NFC East.

Ware suffered a quadriceps strain Sunday and Murray left with a sprained medial collateral ligament in his left knee. Both had MRIs Monday.

After the game Ware said he was fine and was walking without a limp. He has played in 134 straight games making 133 starts. The only start he missed came Dec. 19 2009 against the New Orleans Saints when he had two sacks in a reserve role. Through six games this season Ware has had to deal with a recurring stinger back strain dehydration getting poked in the eye and now the quadriceps strain.
