Arkansas' Bielema on spies: 'If they're wearing an Auburn shirt, knock the s--- out of them'

Bret Bielema knows how to play to a crowd.

The Arkansas head football coach had some fun with fans over the weekend at the expense of the rival Auburn Tigers.

Bielema took the microphone before a public scrimmage on Saturday, telling Razorback fans to watch out for spies.

"If you see someone videotaping, tell them that ain't right," Bielema said, via NWA Online. "Especially if they're wearing an Auburn shirt, knock the s*** out of them."

Fans cheered Bielema for the line.

The Razorbacks and Tigers will help kick off the SEC season on Aug. 30, when they clash at Jordan-Hare Stadium.
