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.
"I just pray every morning, every night I'm pain free and hope the cycle goes away and allows me to play football," Knighton said. "The past few weeks, I've been having them at home, been curled up basically trying to pull my hair out in tears. Luckily, I haven't had them in a game, but if I did, I'd have to take myself out. I've been feeling better during the day. At night, I'm having problems sleeping."
