Griffin was sidelined for the first two games of the opening-round series with a sore left knee.
The six-time NBA All-Star exited Detroit's penultimate game of the regular season against the Memphis Grizzlies on April 9 after 18 minutes of action and hasn't suited up since.
It was previously reported that Griffin was likely to miss the entire first-round matchup against Milwaukee due to his injury.
Griffin averaged 24.5 points, 7.5 rebounds, 5.4 assists, and 0.7 steals on 46.2 percent shooting across 75 appearances in his first full season with the Pistons.
Milwaukee currently leads 2-0 in the best-of-seven series following a pair of blowout victories at the Fiserv Forum.
