It's unclear what exactly happened, but Blount headed for the locker room shortly after Detroit went through a couple rounds of Oklahoma drills. He was walking under his own power, though escorted by a trainer.
The practice was Detroit's first in pads, and several players noted how intense it was, both as compared to the last two days of practice as well as last year, the story said. New coach Matt Patricia is trying to ramp up the physicality, and that was easily evident in a series of blocking and hitting drills that were unveiled Sunday. That includes the Oklahoma drill, which was not run under former coach Jim Caldwell.
