Rookie James says he will be back at 49ers practice Monday

San Francisco 49ers rookie running back LaMichael James said on his social media account his injury Saturday was not serious and he will be back at practice Monday.

"I will be 100% at practice Monday In full force believe that go 9ers thanks for all the support I love you guys!" James tweeted Saturday night after he was carted off with a leg injury.

James, a second-round draft pick from Oregon, suffered an ankle injury during the fourth quarter. Coach Jim Harbaugh said after the game that X-rays showed no damage to the ankle and expected James to be available to practice soon.

The prognosis wasn't as good for veteran Brandon Jacobs, who suffered a left knee injury when he was hit by a helmet during a first quarter run. He is expected to return some time this season.
