49ers quarterback Colin Kaepernick will play one or two series, but no more than a quarter, against Denver on Thursday, reports the San Jose Mercury News. Coach Jim Harbaugh said Scott Tolzien, Colt McCoy and B.J. Daniels will get the rest of the snaps as they vie for the backup job.
"It's very even," Harbaugh said. "I'm really looking forward to the games and future practices determining that."
