ALLEN PARK — Lions running back Jahvid Best, who on Sunday suffered his second concussion in three months, didn’t practice on Thursday.

There is talk he may be done for the season.

Mike Freeman of CBSsports.com has reported that people close to Best are telling him “that he needs to strongly consider sitting out the year.’’

Best has a concussion history going back to Cal where he missed the final four games of his senior season with a severe concussion.

His concussion history was a red flag when he was drafted by the Lions in the first round in 2010, but they said they had done their due dilligence through testing.
