Detroit Lions running back Javhid Best expects to learn Friday whether he'll be cleared to resume playing.
Best underwent a battery of tests administered by a neurologist on Monday after suffering his second concussion of the season when he was injured in the Lions' loss to San Francisco. If the news is positive, he could be removed from the physically unable to perform list on Monday.
The Lions' next game is Oct. 22 against Chicago.
Asked why it has taken so long to receive medical clearance, Best wouldn't say specifically but indicated there were no signs of a problem. He does know there's a heightened awareness around the league regarding concussions.
"I think it's just timing," he told reporters Thursday. "The situation I'm in now with the way the concussions are being taken right now is taking a long time and it's a long process right now. I have to take it how it is. Tomorrow, I find out what's the next step."
Lions offense coordinator Scott Linehan would love to have Best back.
"You all have seen Jahvid when he's played and he's as explosive a player as I've been around," Linehan said. "We're excited about the prospect of him possibly coming back but we're also tempering that enthusiasm knowing that a lot of things have got to be done before that happens."
