Second-year defensive end Tyrone Crawford was carted off the field Sunday during the Cowboys' first practice of training camp.
He was participating in slalom drills against tackling dummies when he fell to the ground and yelled in pain. He held his left ankle and lay on his back, pounding the ground in anger. "Achilles!" he told the trainers. "I can't --- believe this!"
For the Cowboys, it was a second blow for the defensive line in two days. Saturday, defensive tackle Jay Ratliff suffered a hamstring injury during the conditioning test. The Cowboys may now be forced to shore up the depth in the defensive line, an area owner Jerry Jones said in the offsesaon that he liked.
It could put the Cowboys in the market for veteran defensive end John Abraham, who spent last season with the Atlanta Falcons. He was released in March after completing one year of a three-year extension he signed in 2012. He is the Falcons' career sacks leader.
