Jahvid Best has battled concussions since playing in college, and his most recent one could cost him the rest of the season. He is currently listed as day-to-day with a concussion and has missed the last two days of practice in preparation for Sunday's game with the Atlanta Falcons. He is now being advised to sit out the rest of the year, lest he have career-threatening issues:
NFL Insider Mike Freeman reported Thursday that Lions RB Jahvid Best has been advised by people close to him to "strongly consider sitting out the year" after suffering his second concussion of the season.
Best missed the final four games of his college career after a frightening concussion that knocked him cold as he scored a touchdown. Best has been the Lions' leading rusher so far with 390 yards and two touchdowns.
