Randy Gregory appears to have high ankle sprain

ARLINGTON, Texas -- Rookie defensive end Randy Gregory left AT&T Stadium Sunday night after the Cowboys’ 27-26 win over the New York Giants with a walking boot on his right foot.

Executive vice president Stephen Jones said Gregory appears to have a high ankle sprain, but added a complete diagnosis won’t be known until Monday.

“I’m icing it and I’ll get treatment,” Gregory said, “and we'll see how it goes."

A high ankle sprain can keep a player such as Gregory, who relies on speed, out of action for several weeks.

Gregory did not record a tackle, but he had several good pass rushes and hit Giants quarterback Eli Manning once.

“I absolutely like what we had seen tonight,” Jones said. “He was getting some pressure and playing against a hell of a quarterback who knows how to get rid of the ball."

The Cowboys tried to upgrade their pass rush in the offseason by drafting Gregory, a first-round talent who slipped into the second round because of off-field issues.

He had been one of the stars of training camp, and the Cowboys were hoping his presence would ease the loss of defensive end Greg Hardy, who’s serving a four-game suspension to start the season for violating the league’s personal conduct policy.

Now the Cowboys will rely on Jeremy Mincey, who had a team-high six sacks last season, and DeMarcus Lawrence, a second-round pick in 2014, to provide the pass rush.

The Cowboys also used Jack Crawford at defensive end in some passing situations. Defensive tackle Tyrone Crawford had the Cowboys’ only sack against the Giants.

“I did some things well. I felt like I wasn't out there a lot, but in the limited time I was out there I had some good rushes,” Gregory said. “Overall, I think I did a decent job for the first game.

“I’ll get a lot more feedback from the coaches and look at some film and try to get better."
