The defensive linemen and linebackers took their turn working out at the combine on Monday, but the biggest news for the Big 12 was who wasn't on the field.

Former Kansas State linebacker Arthur Brown was in uniform and in attendance, but didn't complete a full workout due to a shoulder injury. That was unforeseen, but here's hoping Brown gets a chance to show off his measurables at Kansas State's pro day in Manhattan later this month. I'm betting he impresses.

A few numbers of note from the top performers on Monday:

40-yard dash

• A.J. Klein, LB, Iowa State: 4.66 seconds, 13th among linebackers/D-linemen

• Tom Wort, LB, Oklahoma: 4.78 seconds, 25th among linebackers/D-linemen

225-pound bench press

• Stansly Maponga, DE, TCU: 30 reps, 11th among among linebackers/D-linemen

Broad jump

• Arthur Brown, LB, Kansas State: 116 inches, 28th among linebackers/D-linemen

Three-cone drill

• Tom Wort, LB, Oklahoma: 7.41 seconds, 13th among linebackers/D-linemen

The Big 12's biggest assets all year were on the offensive side of the ball, so it's no big surprise to see an average performance at the combine from its defenders. Texas' Kenny Vaccaro will probably be the league's first defender drafted, but defensive backs will close out the combine later this week. See more results here.
