Most of the focus for Washington's division title game in Philadelphia centers around who will suit up at quarterback for the Burgundy and Gold.
That's a huge issue - obviously - and Washington will have a clear advantage if Alex Smith is able to return from the calf injury that's cost him the last two starts. Washington is 4-1 in games Smith starts, 2-8 in games he doesn't start.
Beyond that, however, looms the Eagles talented defensive tackle Fletcher Cox.
A six-time Pro Bowler that was named to the 2010s All-Decade team, Cox would be widely regarded as the best defensive linemen in the NFL if it wasn't for the Rams' Aaron Donald.
Cox has also dominated Washington - in 17 career games against the football team, he has 12.5 sacks, 23 QB hits, 13 tackles for loss, three forced fumbles, two fumble recoveries and at 6-foot-4 and 310 lbs, Cox has even scored a touchdown against Washington.
The good news for Sunday night? Cox might not play.
He went into last Sunday's game against Dallas with neck issues, and left the Eagles loss to the Cowboys after the first quarter with a stinger. It's no coincidence that with Cox in the game, Philly held a 14-3 lead, and after Cox's injury, Dallas dominated the scoring 34-3.
Cox missed practice on Wednesday, and with the Eagles mathematically eliminated from the playoffs, it might make sense to shut the big man down for the season.
That would be tremendous news for Washington. So while the folks inside the beltway sweat out the news at QB, pay attention to what's happening in Philly too.
