Detroit Lions running back Jahvid Best continues to work his way back from a brain injury, but if he is not healthy he may end up on the physically unable to perform list.
Best has not played in a game since Oct. 16, when he suffered his second concussion of the year in a loss to the San Francisco 49ers.
If Best starts the season on PUP, he will be required to miss at least the first six weeks and after that he can be activated. The earliest Best could play would be Oct. 22. The Lions play the Chicago Bears on Monday night.
“Particularly with concussions, time is always beneficial,” Lions head coach Jim Schwartz told the Detroit Free Press. “We’ve seen that with a lot of other guys that have come back and that would buy us time if we had to cross that hurdle.He’s working out hard, he’s just not cleared (for contact) yet."
