SANTA CLARA -- Quarterback Colin Kaepernick is experiencing what has been described as a “tired arm,” “arm fatigue” and a tight throwing shoulder.
But there is no indication Kaepernick is experiencing “dead arm syndrome,” which is defined as sensory reduction or loss in the arm as the result of a shoulder dislocation or subluxation.
ESPN’s Adam Schefter, citing two sources, reported Monday that Kaepernick is dealing with “a dead arm.”
Kaepernick did not practice Thursday and Friday, then was held out of the 49ers’ exhibition opener Sunday against the Houston Texans. Kaepernick’s condition appears to be a result of usage, not from a hit or dislocation.
