Before Colton McKivitz reported to 49ers training camp and a pivotal contract year, he ran San Francisco’s North Beach hills to condition himself physically and mentally.

The former Nebraska football wide receiver failed to land a spot on the 49ers initial roster after the opening week of training camp in San Francisco.

The San Francisco 49ers have added more depth to their wide receiver room, bringing in former 1,000-yard receiver Robbie Chosen. On Sunday, the 49ers announced that they have signed Robby Chosen (formerly Robbie Anderson) and released fellow wide receiver Marquez Callaway. The latter was just signed by the 49ers earlier this week.
