Mason, 27, is 5-foot-11 and is the former G League MVP. He has been a journeyman of sorts for his NBA career, having spent time with the Kings, Bucks and Magic since being a second-round pick out of Kansas in 2017.
He has compiled NBA averages of 6.7 points, 2.6 assists and 2.0 rebounds in a total of 103 career NBA games. His deal with the Lakers is likely non-guaranteed.
The Lakers will not need to make a corresponding move after signing Mason, as they have an open spot on their 20-man roster. They currently have 13 players on guaranteed deals, with two available. There is a chance they could carry just 14.
