The Lions coaching staff held its breath for a bit Saturday when third-round pick Larry Warford went down in pain during an 11-on-11 drill. The offensive lineman walked off the field with the trainer holding his left arm and, though he didn't finish the practice, he was back on the field for the post-practice meeting. "I don't think it was a shoulder," coach Jim Schwartz said. "It wasn't serious enough to keep him in (the trainer's room). He stayed around. He caught an elbow that hurt."
