The NFL says that Dallas' matchup with rival Washington on Dec. 30 would be on NBC's "Sunday Night Football."
Starting in Week 11, the league's flexible scheduling policy allows it to move a more appealing game to Sunday night. This is the second time this season a switch has been made.
The Cowboys are 8-7 heading into their trip to Washington, which beat the Cowboys 38-31 on Thanksgiving. The Redskins are 9-6.
Another matchup with playoff implications, Packers-Vikings, shifts to 4:25 p.m. ET on Fox.
Elsewhere, CBS has moved the Dolphins-Patriots game from 1 p.m. ET to 4:25 so, sources told ESPN NFL Insider Adam Schefter, that the AFC seeds can't be completely locked in by the 1 p.m. results.
