Perhaps it was someone on the Washington Redskins that reminded the Browns' rookie quarterback of certain inadequacies he has displayed during summer training camp.
Or perhaps he suffered a cramp in his hand.
In any event, the former Heisman Trophy winner has been fined $12,000 by the National Football League for making an obscene gesture towards the Redskins' sideline this past Monday night during a preseason game outside our nation's capital.
When he was quarterbacking the Browns Monday night, Manziel completed seven of 16 passes for 65 yards and a touchdown in the 24-23 loss to Washington.
Prior to that, the Texas A&M product had thrown for 63 yards on seven of 11 passing in a one-point exhibition loss to Detroit. Manziel and the Browns will host the St. Louis Rams in Cleveland Saturday night in the team's third preseason game.
Manziel made himself available for the 2014 NFL Draft this past May after his second season of college football and was the 22nd overall pick in the first round.
Browns head coach Mike Pettine announced this week that Brian Hoyer will be the team's starting quarterback when Cleveland opens its 2014 season on Sept. 7 against the Pittsburgh Steelers.
