He hasn't practiced yet this training camp because of a sore left toe that he said has caused problems in leg muscles. Dansby was walking out of the team's facility Monday with a rolling bag that contained a treatment device that he said is helping. "It's a serious injury," he said. "They say (it could be a) career-ending injury." Dansby said the problem is in the bone of his big toe. Dansby said he feels much better now than he did a few weeks ago.
