Colin Kaepernick

Colin Kaepernickis ready to get on the field again.

In anInstagram poston Tuesday, rapperJ. Coleshared a copy of a letter that Kaepernick, 35, wrote to New York Jets general manager Joe Douglas requesting to join the practice squad. Kaepernick’s lawyer confirmed to PEOPLE that the letter was from the quarterback.

“I asked Colin @kaepernick7 if I could share this letter with the world. He was reluctant,” explained the musician, 38, in the post’s caption. “My argument was that I believe the people and all organizations should know the truth about how hard he works and how much he still wants to play. And always has. In the end, he agreed to let me.”

Kaepernick last played in the NFL as a member of the San Francisco 49ers during the 2016 season. When the national anthem played at the beginning of each game, Kaepernick begantaking a kneeto protest racial injustice and police brutality.

While he received support from some of his fellow athletes in what was referred to as the#TakeAKnee movement, he alsoreceived backlash, causing him toopt out of his contractin March 2017.

In his letter dated Sept. 21, Kaepernick expressed his desire to join the Jets organization and “lead the practice squad.”

“I would do this with the sole mission of getting your defense ready each week,” he wrote. “If I were able to fill this role for the team, I believe this allows for multiple things.”

Kaepernick explained that he was reaching out to the organization “in response to the unfortunate loss ofAaron Rodgers.”

Rodgers, 39,tore his left Achilles tendonduring the Jets' season opener. While heunderwent a successful surgeryfollowing the injury, he announced in apost on Instagramthat it had taken him out of action for the remainder of the season.

“I know the aspirations this season were, and still are, to win a championship, and so that Hall of Fame sized hole will need to be filled as best as possible to keep the team on a Super Bowl track,” wrote Kaepernick.

“I am sure of my ability to provide you with an elite QB option if, God forbid, QB1 goes down,” wrote Kaepernick. “However, I know that there may naturally be uncertainties from you and possibly from others about my playing abilities. This plan, I believe, allows me to be of great service to the team as a practice squad QB while also giving you a low-commitment chance to assess my capabilities to help in any other capacity you may see fit.”
