Their pride clearly took a hit (right Jim Schwartz?) and so did their running game when Jahvid Best was knocked out of the game with a concussion in the fourth quarter.

Fresh off a career performance in Detroit’s spirited Monday night win against Chicago, the second-year back managed only 37 yards on 12 carries before he was replaced by backup Maurice Morris.

Injuries have always been the knock on Best, who despite a wealth of talent has had difficulty staying on the field. He missed games at Cal after a horrific fall that resulted in a concussion and sustained another concussion this preseason.

As The Detroit News reported, Best was not made availble to the media per NFL policy, but the Lions did confirm he was concussed.

Best played in all 16 last season but was limited by a nagging turf-toe injury, which contributed to his meager 3.2 yards per carry average.

This season Best has been a vital part of Detroit’s high-flying offense. Through six game’s he’s averaging 4.6 yards per carry and also has 27 receptions for 287 yards.
