The 49ers' two injured running backs were in high spirits today but are getting around in different ways.
LaMichael James, who injured his ankle late in Saturday's loss to the Texans, walked off the field following a morning walk-through without a limp. James insisted after the game that he'd be ready to take part in today's afternoon practice. Jim Harbaugh, however, said, "we'll see" when asked about James' availability. The bottom line is that it doesn't seem like James will miss any significant time.
Brandon Jacobs, meanwhile, was getting around with the help of a pair of crutches. As he passed through the locker room, Jacobs said, "I'm doing good. I can't complain." Teammate Frank Gore said that Jacobs would probably miss "a week or two" after taking a hit to his left knee in the first quarter Saturday. Harbaugh, meanwhile, was asked if Jacobs would be ready for the Sept. 9 season opener.
"Brandon for the opener?" he said. "It's possible. Again, we just have to see how the treatment goes, how the body responds."
Jacobs is unlikely to play in the 49ers' final preseason games - in Denver and at home against the Chargers. Through two weeks, the 49ers lead the league in rushing in the preseason, averaging 189 yards per game on the ground.
The team's depth at running back also is evident. The 49ers may lead the league in rushing overall, but their highest individual running back, Kendall Hunter, ranks 18th overall. Quarterback Colin Kaepernick, who had a 78-yard touchdown run against the Vikings, is tied for fifth overall among all rushers.
