ASHBURN — Washington Redskins nose tackle Terrance Knighton did not participate in Thursday’s practice, along with cornerback Will Blackmon and safety Trenton Robinson.
Knighton was at a follow-up appointment for his cluster headaches, which prevented him from traveling to play the New England Patriots on Nov. 8.
“He’s had some symptoms, but he’s been able to deal with them,” coach Jay Gruden said on Thursday. “It’s just a routine checkup. It’s the only time he could get in to see [the specialist]. Hopefully they’ll find some answers for him.”
In last week’s 47-14 win against the New Orleans Saints, Knighton returned, but only played 11 snaps. The cluster headaches affect Knighton mostly while he sleeps. On Wednesday, Knighton said he was feeling better and was able to get approximately three hours of sleep — a big improvement from the one hour he said he was getting each night in the week leading up to the Patriots game.
Robinson did not participate because of a hamstring injury he sustained in Sunday’s win against New Orleans. Blackmon was absent because of personal reasons.
Inside linebacker Keenan Robinson (stinger) and cornerbacks DeAngelo Hall (sprained toe on right foot) and Chris Culliver (sprained left knee) were limited in practice.
