Smith last played in the NBA for the Cleveland Cavaliers in November 2018. He'll serve as a replacement for Avery Bradley, who opted out of the NBA return in Florida for personal reasons.
The 34-year-old joins forces once again with former teammate LeBron James. Smith was a key contributor during the Cavaliers' 2016 title run, pouring in 14 3-pointers and scoring double-digit points in each of the last five games of the Finals against the Golden State Warriors.
For his career, Smith is averaging 12.5 points on 37% shooting from beyond the arc.
