Keith Harrington starred on Thursday Night Football again. That's not unusual. But he did it in an unusual setting today.

Because of a suggestion to coach Mike Leach made by injured quarterback Connor Halliday during a recent phone call, the Cougars have practiced indoors all week to prepare for the unseasonably warm temperature they'll play in this weekend.

We've got a report from WSU's weekly underclassmen scrimmage after the jump.

…

Reporters were allowed to attending the first 15 minutes of practice, as well as Thursday Night Football, but the majority of practice was closed. A source deep inside the program indicated that Peyton Bender's pass of about 70 yards to Gabe Marks was the highlight.

We also noticed that Nick Begg, Dylan Hanser, Sulaiman Hameed, Mack Hopkins and Nate DeRider appeared to be limited.

Marks had a couple highlights during the scrimmage as well, showing the young defensive backs what a successful starting Pac-12 receiver looks like. He led the team in receiving last season, after all, before redshirting this year.

"If they're not fired up to go against that guy that's been in a lot of big games, and have a chance to compete with him, then they shouldn't be out here," said linebackers coach Ken Wilson.

The best plays of the scrimmage, however, came courtesy of Harrington and they came back-to-back. On the first play he took a quick pass in the backfield, ran to the right and then juked to the left, passing Willie Roach and giving himself lots of grass. The next play was a handoff and he weaved his way for about 25 yards up the middle of the field.

Defensively the biggest play came courtesy of Chandler Leniu, who intercepted Connor Ennis' pass and returned it for a touchdown.

"He's getting in shape. He's playing his way into shape," said Wilson of the redshirting freshman. "He's doing a good job using his hands, learning the defense and he's playing harder all the time as he gets in condition. He's going to be a force if he keeps working."

Sebastian LaRue was seen working with the wide receivers earlier in the week but played cornerback today and made a nice play, closing on receiver Zaire Andre quickly after he made the catch and dragging him to the ground with violent authority.

LaRue, a who was highly thought of as a receiving prospect when he signed with Texas A&M out of high school, started off on offense and it appears the Cougars still think it's worth giving him a look there. But his future, for now, appears to be on the defensive side of the ball.

"I think Sebastian will be a heck of a defensive player," Wilson said. "Sebastian will do a lot of things. He dabbles in kick returns, punt returns. One day he does individual (drills) with the running backs, one day he's with the receivers. He's a multi-talented gu
