Colin Kaepernick's arm strength and conditioning stood out in his workout with the Las Vegas Raiders, but no signing was imminent as of late Thursday night, sources told ESPN.
The Raiders considered Kaepernick's workout a 'positive,' a source said. Las Vegas could be looking for another passer to serve as the backup for Derek Carr despite trading for former New England Patriots quarterback Jarrett Stidham and signing Nick Mullens.
In NFL team workouts, quarterbacks typically throw the route tree on air, implement team-specific offensive principles on the field and meet with coaches.
