SANTA CLARA -- Pierre Thomas' spin move appears to be in mid-season form.
The new 49ers running back, who hasn't had a carry since Dec. 15, cruised through the locker room Thursday, turned to reporters and, still in stride, said, "Sorry, guys, I'll talk to you tomorrow."
He and Shaun Draughn, after all, are going through a day-and-night cram session to get ready for Sunday's game. Offensive coordinator Geep Chryst said Draughn may be a day ahead of Thomas in learning the game plan but only because he arrived on Monday whereas Thomas was signed Tuesday.
Both could see plenty of work against the Falcons. Mike Davis is still on the active roster but won't play after undergoing surgery on his hand Tuesday. The team has not revealed its plan for starter Carlos Hyde, who is dealing with a stress fracture on the side of his foot. If he sits out Sunday's game, he will have a month off by the time the 49ers next play on Nov. 22 because their bye is next week.

The only other runner is Kendall Gaskins, who was on the 49ers practice squad at this time last week and who rushed five times for six yards in Sunday's loss to the Rams.
Draughn, who has been on the active roster of seven different teams, said that varied background would help him adjust quickly to what the 49ers run.
"I've been in a lot of different systems," he said. "Everybody runs pretty much the same (things). It's just a matter of what dose they're running it. Are they running it a majority of the time or what?"
Of the two newcomers, Draughn was playing more recently. The Browns cut him last month, and he still was in Cleveland when the 49ers called him at 6 p.m. Sunday.
"I left Sunday night," he said. "I left around 9, got on the plane and I was here Monday morning."
Draughn is wearing No. 24; Thomas has No. 32.
