Commanders head coach Dan Quinn said that Seibert (hip) won't participate in Tuesday's practice, Nicki Jhabvala of The Washington Post reports.
Seibert will only have one more chance to log some practice reps this week, but his lack of activity Monday and Tuesday is putting him at risk of missing a second straight game this Thursday versus the Eagles. While Seibert was sidelined for a Week 10 loss to the Steelers, Zane Gonzalez handled kicking duties and connected on both of his field-goal tries and all three of his extra-point attempts.
