The life of a veteran backup quarterback in the National Football League can be pretty mundane. You attend all the meetings and film study with the starters, you get a few reps with the second team in practice, and come gameday you’re standing on the sideline with a visor and a clipboard.

It’s certainly not a bad gig by any stretch of the imagination, but sometimes you have to have a little fun with it. Just ask nine-year NFL backup QB Chase Daniel, who signed with the Chicago Bears this offseason and is still getting familiar with his new teammates.

Wearing a #10 Mitchell Trubisky jersey, bucket hat and sunglasses, Daniel fooled several of his teammates at a recent practice as he blended in with a crowd of young Bears fans looking for autographs from players and coaches. Among the players that didn’t recognize Daniel off the top was none other than his fellow QB, Trubisky, who signed the jersey before turning to the camera and asking “who is that?”

Trubisky, entering his second season in the NFL, went 4-8 in 12 starts for the Bears last season, throwing for 2,193 yards with seven touchdowns and seven interceptions.
