Chip Kelly and Trent Baalke have differing opinions on why Colin Kaepernick lost his job last season as starting quarterback of the San Francisco 49ers.

“It’s not like his skill set diminished," Kelly told Denver's 9 News Tuesday. "I mean he went on injured reserve last year. He only played half the season. He was legitimately injured. He’s in the process of rehabbing right now – he had a shoulder, had a thumb, had a knee. That’s where when people look at where he fell off -- he didn’t fall off. He got hurt."

When Kaepernick went to injured reserve, Baalke claimed the injury had nothing to do with the benching.

Kaepernick suffered the shoulder injury -- a torn left labrum -- in an Oct. 4 loss to the Packers. The thumb tear came Oct. 22 against the Seahawks and the knee injury in the following game against the Rams.

Kaepernick's agents have been seeking a trade, but Kelly continues to lobby for him to remain with the 49ers.

Kelly said he's spoken regularly to Kaepernick and that the quarterback "knows I'd love to have him."
