IRVING, Texas -- Defensive tackle Sean Lissemore returned to practice Tuesday after missing a week with a groin injury.
Lissemore did some individual drills and coach Jason Garrett said the Cowboys will work him into some team drills later this week.
In terms of playing in Saturday's fourth preseason game against the Cincinnati Bengals Saturday at AT&T Stadium, Lissemore said, "I'm planning on it."
With Jay Ratliff out with hamstring and groin injuries, Lissemore took over at one of the defensive tackle spots. In the offseason, Lissemore had to make a switch from 3-4 defensive end to a 4-3 defensive tackle who will take on centers and protect the run.
"I think I can play in this defense," he said. "It's different from the two-gap scheme, but it's forgetting everything I've learned the last three years."
Lissemore thought he needed to pick up weight, but instead the Cowboys' coaches said he needed to lose some to become faster.
"I'm down 12 to 14 pounds from where I was at the start of training camp," Lissemore said. "I'm at 298 pounds, and I have to play the run on the way to the pass."
The Cowboys value Lissemore's ability to back up Ratliff when he returns. During practices and before he was injured, Lissemore was talking to Ratliff about the finer points of playing defensive tackle.
"I get everything from him," Lissemore said. "He's been a great teacher and he's always there for me."
