Tight end Zach Ertz and safety Jeremy Chinn are questionable for the Washington Commanders' division matchup with the Philadelphia Eagles this Sunday.

Both Ertz and Chinn left last weekend's game against the New Orleans Saints with concussions. Ertz headed to the locker room after his head hit the turf on a one-handed, 19-yard reception in the second quarter, while Chinn went down following a collision on a 25-yard catch by Marquez Valdes-Scantling.

Chinn was back at practice on Wednesday wearing a black "no contact" jersey and was listed as limited on the injury report. Ertz returned after taking Wednesday off and also wore the black jersey. Both players were full participants on Friday.

The Commanders are prepared for the possibility of one or both players being out for Sunday's game, but Chinn and Ertz provide each side of the ball with a unique skill set that is hard to replace. Chinn has been a physical player for the Commanders' defense and played in all of the team's defensive snaps in the previous five games.

Ertz, meanwhile, brings veteran leadership and all-around talent that has been a boon for the Commanders all season. Ertz has been one of Jayden Daniels' favorite targets with 54 catches and four touchdowns.

"He's just a guy that's a safety net for a quarterback at all times," said offensive coordinator Kliff Kingsbury. "He has a knack for getting open, knack for making the big play, and so I didn't think we handled that [replacing him against the Saints] great. As a coaching staff we got to have better answers if something like that happens, because he's such a vital part of what we've been doing this year."

The Commanders will need both Ertz and Chinn on Sunday against the Eagles, who have built a top 10 offense and defense while winning a franchise record 10 straight games.

Kicker Zane Gonzalez will be available for the Commanders after being ruled out against the Saints. Gonzalez missed practice on Wednesday for personal reasons but was a full participant on Thursday and Friday.

Both guard Sam Cosmi and tight end John Bates missed practice at various points this week while recovering from an illness but will be available for Sunday's game.

Defensive tackle Jonathan Allen is the only player who has been ruled out against the Eagles, head coach Dan Quinn confirmed in his Friday press conference. The Commanders opened the 21-day window for Allen to be returned to the active roster at some point this season. Allen underwent surgery to repair a partially torn pectoral muscle he suffered against the Baltimore Ravens.

Allen impressed both Quinn and defensive coordinator Joe Whitt Jr. with how physically prepared he was during his first week of practice in almost two months, but Quinn said Allen is not ready to suit up just yet. There is optimism that he will be available for Washington's Sunday Night Football matchup with the Atlanta Falcons, which will have significant playoff implications for both teams.
