Dockery, who made his first start of the season at guard in place of Bill Nagy, wasn't sure how long he would be sidelined. Nagy returned to practice Thursday as he recovers from a neck injury.
"I wanted to be out there so bad," Dockery said. "I was looking forward to getting back out there on the practice field -- coming in Monday, Tuesday and Wednesday and doing some extra things to help me on the field. To find out that this was happening to me was disappointing, but I'm in good spirits."
