Though Best had two documented concussions at Cal, and two more last season, he insisted to Dave Birkett of the Detroit Free Press that he’s only been diagnosed with three. Best claims he’s “not at all concerned” about his concussion history.
Doctors do seem to be, however, seeing as Best has yet to be cleared for contact.
Lions G.M. Martin Mayhew stated in May that the team hoped Best would be medically cleared in June.
Best now says he probably won’t get clearance until just before training camp.
The first of Best’s two 2011 concussions occurred during the preseason. He suffered another in October, and hasn’t played football since. He has been participating in individual drills during OTAs.
