Washington linebacker London Fletcher's streak of 234 consecutive games played appears safe.
The 15-year veteran who has never missed a game was listed as active Thursday against Dallas. Fletcher sprained his right ankle last weekend against Philadelphia and had just five days to try to recover.
The 37-year-old is tied with Tampa Bay's Ronde Barber for the longest current streak in the NFL.
Dallas running back DeMarco Murray will miss his sixth straight game with a sprained right foot.
Cowboys right tackle Tyron Smith was active. He sprained an ankle Sunday against Cleveland and said he was likely a game-time decision.
Dallas nose tackle Jay Ratliff was inactive because of a groin injury. He missed the first four games of the season with a high ankle sprain.
