Discord between Kaepernick and the 49ers appeared after Harbaugh left to coach Michigan at the end of the 2014 season. Kaepernick didn't seem to have the same chemistry with coach Jim Tomsula, who was fired at the end of last season.However, new coach Chip Kelly seems willing to work with Kaepernick and get everything back on track."I'm a big Kap fan," Kelly said. "I'd love to have him."Harbaugh, who has remained close to Kaepernick since his departure, said his ability to work through injuries is what prompted him to draft Kaepernick in 2011.The Bee reported Kaepernick dealt with a stress fracture in his left leg at Nevada and had a chipped bone and ruptured capsule in his foot in 2013. He also battled a torn labrum in his left shoulder, a tear in his right thumb and needed to have his left knee cleaned out all during 2015."He's as tough as nails,"

Harbaugh said. "That's a badge of honor in a lot of ways."
