Colin Kaepernick To Work Out For Las Vegas Raiders

Colin Kaepernick could be back in the NFL as early as next month ... 'cause the quarterback has scheduled a workout with the Raiders -- and if it goes well, the team could sign him to a contract.

ESPN's Adam Schefter just broke the news ... reporting the tryout will go down in just a few days.

Kaepernick has been preparing like a madman for this for years -- but has recently ramped up his workouts in the last few months for this specific moment.

As we reported, the 34-year-old has toured the country since the end of winter a few months ago, throwing to wide receivers in various cities weekly.

And, at one of his most recent stops in Washington, he pleaded with NFL GMs to just give him a tryout ... explaining, "I think my talent, my skill set will speak for itself."

The Raiders' owner, Mark Davis, has always been open to giving Kaepernick that chance -- saying back in April he believed the guy could still play.

"If our coaches and general manager want to bring him in or want him to be the quarterback on this team," Davis said, "I would welcome him with open arms."
