Lions running back Jahvid Best, who has not played since suffering another concussion last October, likely will start this season on the physically unable to perform list and miss at least the first six games, according to Adam Schefter of ESPN who cites a source familiar with the situation.
Doctors still have not cleared Best to play, a surprise to some Lions officials but evidence of how carefully Detroit is bringing him along.
The 23-year-old Best and the Lions have received different opinions from different doctors, but the team does not want to rush him back to action. Best suffered at least two concussions last year, one in the preseason and another against the San Francisco 49ers on Oct. 16.
Best also suffered at least one significant concussion during his last college season at California, and some NFL teams took the running back off their draft board due to concerns about his brain injury.
