New England Patriots quarterback Tom Brady had an unusual addition to his pre-snap signals for Monday night's game against the Buffalo Bills.
Lining up behind the center during the first quarter, Brady started barking out play calls when he shouted "Rex Ryan!"
The Bills coach has been a longtime rival of the Patriots. He coached the AFC East New York Jets from 2009-14.
Brady is 10-4 in his career against teams coached by Ryan, a former Ravens defensive coordinator.
