"Right now, I weigh 270," Mark said.
Mark did not lose weight due to a viral infection as had been reported elsewhere.
"I was at 290 the beginning of the season, but it's just through the hard work and all the training and stuff like that, getting into football shape. I'm just cutting down on all the fat and then building up with muscle."
He hopes to reach his target weight, 290 pounds, "sometime during the season".
