Head coach Jay Gruden has been trying to get Griffin to play at a faster tempo, which sparked the decision to make the change to the wristband. According to the AP, Washington leads the NFL with eight delay-of-game penalties in 2014.
"We just wanted to experiment a little bit," Gruden said. "We have some calls that are a little bit wordy, and we just put about five or six runs on there and a couple of play-action plays and a couple of dropbacks, and maybe speed up the process. Maybe for third down where you say, 'No. 5,' he can look at it and read it."
Gruden said wristbands can "help speed up the communication process" and will probably expand the number of plays on the wristband for Sunday's game against the Dallas Cowboys.
The win over the Eagles snapped a six-game losing streak for Washington and was its first win since October.
Griffin completed 16-of-23 passes for 220 and threw an interception in the win.
