David Irving continues to have lingering issues with a concussion he sustained in the Nov. 30 game against the Washington Redskins.
The Dallas Cowboys defensive end has missed the past two games with the injury, and won’t practice again Wednesday, according to coach Jason Garrett. Irving has yet to clear concussion protocol.
Irving sustained the concussion in the first quarter against the Redskins, but played through it. He sacked Redskins quarterback Kirk Cousins late in the fourth quarter before being diagnosed with the concussion.
Irving posted an update on his Twitter account Wednesday, writing: “Mentally I’m fine ... I’m still having headaches every day. It’s hard to put a finger on how long I’ll be out. I’m taking it day by day.”
Never miss a local story.
With Irving out the past two games, Maliek Collins has played the under tackle spot with Richard Ash at nose tackle.
Irving still ranks second on the Cowboys with seven sack and has been credited with 12 tackles, three tackles for loss and 19 quarterback pressures. He missed the first four games of the season for violating the NFL’s performance-enhancing drugs policy.
Left tackle Tyron Smith (right knee) also won’t practice. Smith, who was named to his fifth consecutive Pro Bowl on Tuesday, usually doesn’t practice on Wednesdays, and the knee injury is another setback for him.
“He hurt his knee in the game and wasn’t able to finish. It looked like a little bit of a hyperextension,” Garrett said. “He seems like he’s getting better. He’s moving around, he’s been out at walk-throughs, he’s engaged in what we’re doing, so we’re hopeful as the week goes on he’s going to be able to move around well enough to play.”
Other Cowboys who didn’t practice included defensive end DeMarcus Lawrence (back), linebacker Anthony Hitchens (knee) and right tackle La’el Collins (back).
The Cowboys host the Seattle Seahawks Sunday.
