Manziel took offence to comments made by the Redskins and he was caught on camera making a gesture after he threw an incomplete pass late in the third quarter.
"It was hilarious. We were messing with him a little bit, just saying this ain't college and stuff like that. We were having a little fun. Manziel flipped us off. It was something funny. We were all laughing on the sidelines," linebacker Brian Orakpo said, ESPN reports.
Meanwhile, Orakpo was evidently in the mood to antagonise Manziel as he copied his money sign after fellow linebacker Ryan Kerrigan sacked the quarterback.
