"Going out there in that first period of seven-on-seven, it kept on getting tighter and tighter, and it wouldn't loosen up for me," Britt said, according to the Tennessean. "I got a little scared so I backed down."
Britt said he thought the hamstring troubles were a thing of the past.
"I really did (think I was past it)," Britt said. "I hadn't felt nothing since I've been back. It's been feeling great and wonderful every time I got on the field and today, I don't know what it was."
