Colin Kaepernick looking to get back in NFL after settling grievance—and a QB vacancy just opened

Former NFL quarterback Colin Kaepernick is reportedly ready to get back in the NFL now that he has settled his grievance against the league that claimed he had been blackballed for protesting the national anthem.

Kaepernick has not played professional football since 2016, but a source close to the former quarterback said he's ready to go if called upon. The Miami Dolphins traded their starting quarterback Friday, creating a vacancy Kaepernick could potentially fill.

"Yes, he's training hard and ready to play," the source told CBS Sports reporter Jason La Canfora on Friday when asked about the Dolphins.

What's the situation?

The Miami Dolphins traded quarterback Ryan Tannehill to the Tennessee Titans on Friday. They also failed to sign quarterback Teddy Bridgewater, who chose to remain with the New Orleans Saints.

So, Miami's only quarterbacks are the relatively-unknown Luke Falk and Jake Rudock, who have combined to throw only five passes in regular season competition. Needless to say, Miami will need to obtain a quarterback with some experience.

Kaepernick, meanwhile, has been out of the league since after the 2016 season. In the midst of the controversy over Kaepernick kneeling in protest during the national anthem, he opted out of his contract only to find that no other team wanted to sign him for the amount of money he was asking for.

Kaepernick, believing that owners colluded against him to keep him out of the league due to his protests, filed a grievance against the NFL. He recently reached a settlement with the NFL that some have speculated is worth eight figures.

He does not speak to media, so the question of whether he wanted to continue to play football was a subject of speculation. Reports surfaced that Kaepernick asked for unreasonable amounts of money to play in the Alliance of American Football and the XFL.

Now, Kaepernick is reportedly turning his attention back to the NFL. The Dolphins have not commented on whether they would consider signing Kaepernick. There are several other veteran quarterbacks available, and the Dolphins could also pick up a rookie in the draft.
