C.J. Mosley is ready to tackle life beyond playing football.

A five-time Pro Bowl selection during an 11-year NFL career with the New York Jets and Baltimore Ravens, Mosley announced Thursday, his 33rd birthday, that he’s retiring.

Mosley was released by the Jets in March after playing in just four games last season because of a toe injury and later a herniated disk in his neck.

A popular playmaker and leader during his career, Mosley made his announcement with a 2-minute, 10-second video post on his Instagram page titled “Once upon a time ...” that included highlights of his playing career.

“Today, it is time to wake up from my childhood dream and share it with the next generation,” Mosley said. “I spent my whole life and career building my legacy. Now it’s time to start a new chapter with new dreams. It won’t be easy, but I’m here to tell you every sacrifice is worth it.

“When you wake up, what will your legacy look like?”

Mosley, the 17th overall pick by Baltimore in the 2014 draft out of Alabama, had nearly 1,100 tackles with 12 sacks, 12 interceptions, 10 forced fumbles, nine fumble recoveries and three touchdowns.

He played five standout seasons with the Ravens before signing a five-year, $85 million contract with the Jets in 2019 and was the heartbeat of New York’s defense during his tenure as one of the NFL’s top tacklers.

Both the Jets and Ravens posted congratulatory messages for Mosley on social media.

“Captain! Thankful for the memories we couldn’t have asked for a better leader!” former Jets teammate and current Broncos defensive end John Franklin-Myers commented on Mosley’s post.

“Half-Man Half-Amazing congrats on a great career bro,” former Ravens teammate and current Baltimore assistant special teams coach Anthony Levine wrote.

Mosley, who is from Theodore, Ala., was rated as one of the top high school linebackers in the country before heading to Tuscaloosa to play for Nick Saban and the Crimson Tide after getting offers from several top football programs.

He made a quick impact in college, earning Freshman All-American honors, and helped Alabama win consecutive BCS national championships during the 2011 and 2012 seasons.

Mosley also was selected the SEC defensive player of the year and won the Butkus Award in 2013 as college football’s top linebacker.

Mosley became the first Ravens player voted to the Pro Bowl as a rookie.

He made the Pro Bowl three more times before leaving Baltimore for New York and signing what was then the largest free agent deal for an inside linebacker.

Mosley had an impressive debut with the Jets with five tackles and returned an interception by Josh Allen for a touchdown against the Bills, but he injured his groin in the third quarter and played in just one more game that season.

Mosley, who made his final Pro Bowl in 2022, was voted a team captain during each season he played in New York.
