"I feel great. I've basically been cleared for a while now, I've just been stuck at my house," Griffin said during an appearance on The Encore with Sage Steele. "I'm ready to go whenever things pick back up."

The six-time All-Star is in the third season of a five-year, $171-million max contract signed with the Los Angeles Clippers in 2017.
Detroit sat 13th in the Eastern Conference with a 20-46 record when the NBA suspended the season indefinitely in March.
