California star tailback Jahvid Best will not play in the Big Game against Stanford this week as he recovers from a concussion. Coach Jeff Tedford said Monday there is "no chance" Best would play Saturday against No. 14 Stanford. Best sustained his second concussion in an eight-day period when he fell on his back and head from about 8 feet in the air on Nov. 7 against Oregon State. Best returned to the team late last week and was an honorary captain before the Golden Bears beat Arizona last Saturday. Best has 16 touchdowns and 867 yards rushing this season.
