Watch: Gronk opens up about retirement decision on 'The Shop'

Warning: Video contains coarse language

HBO's "The Shop" will return Tuesday night with an episode featuring former New England Patriots tight end Rob Gronkowski alongside Cleveland Cavaliers star Kevin Love, comedian Kevin Hart, rapper Lil Nas X, and others.

In a preview of the episode, Gronkowski opens up about how he decided to retire from the NFL earlier this year.

"I felt in order to do something bigger in life, in order to get to a higher stage - 'cause you're winning the Super Bowl - I felt like I had to get away from the game and focus on my health," he says.

Gronkowski hasn't ruled out returning to football, but it's unlikely to happen anytime soon.
