After Cleveland beat Washington 17-14 Sunday, Portis said "the defense knew every play we were doing" as if the Browns had a copy of the Redskins' playbook.
But Wshington Coach Joe Gibbs and his staff denied the claim, the Washington Times reported Tuesday.
Gibbs said a review of the game found only two instances of the Browns pointing before the snap, and on both plays the Redskins picked up solid yardage.
"You run off the field and say, 'They know what we're running,'" Gibbs said. "In this case, there were two plays I felt like they were pointing to something. They said we were going to run the football. We did run the football and made 4 yards and 8. I didn't see anything like (what Portis said) on film."
Assistant head coach for offense Joe Bugel went further, calling Portis "totally wrong" and telling him to "watch the tape."
Cleveland players said Gibbs' offense was "not that complicated."
