Dallas Cowboys coach Jason Garrett will directly relay plays to quarterback Tony Romo, a change from previous seasons, according to ESPN.
Offensive coordinator Bill Callahan will continue calling plays, but Garrett will have more control over changes by having direct communication with Romo.
Quarterbacks coach Wade Wilson will relocate from the sideline to the upstairs coaching booth with Callahan.
Callahan had called the plays and relayed them to Wilson on the sideline, who then sent them to Romo. NFL rules only allow coaches to communicate with players from the sideline.
Now, Garrett will take the play call from Callahan and relay it through the equipment in Romo's helmet. This also allows Garrett to change the call.
The changes were made during the Cowboys' bye week. They play the New York Giants on Sunday.
