New San Francisco 49ers coach Chip Kelly is waiting to see what Colin Kaepernick can do in his offense, and vice versa. But the QB is losing valuable time as he recovers from offseason surgery, and offensive coordinator Curtis Modkins said Thursday that there's no timetable for his return.

Kaepernick struggled last season, with just six TD passes and five interceptions, and was benched in favor of Blaine Gabbert. He demanded a trade earlier this offseason but still has taken part in workouts, despite being unable to practice following surgery on his left knee, left shoulder and right thumb. He even threw passes for the first time Thursday.

#49ers QB Colin Kaepernick was seen throwing passes for first time on the practice field during warmups. He's still not cleared to practice.

"Whenever they say Colin's healthy, I'm sure he'll be there," Modkins told NFL.com. "He's around us, he's in the meetings, he's doing a great job. It's not up to me when he's released, so we'll see."
