Matt Barrows of the Sacramento Bee is reporting that San Francisco 49ers quarterback Colin Kaepernick will train in Phoenix alongside Kurt Warner and other experts at EXOS.

Kaepernick regressed this season with the 49ers, throwing more interceptions (10) than any other season in his career, matched his lowest average yards per completion (7.0), was sacked a career high (52) number of times, and had his lowest passer rating of the past three seasons.
