Harrell, 27, is in his first season with the Lakers.
While the Lakers were reportedly open to moving Harrell, they opted not to trade him before the trade deadline. He has been a huge help with superstars Anthony Davis and LeBron James sidelined to injury.
On the season, Harrell is putting up 15.2 points and 6.8 rebounds per game. The 2020 Sixth Man of the Year has held down the fort with Davis out of action and Marc Gasol struggling to live up to expectations.
The Lakers recently added two-time All Star Andre Drummond, who should provide help to Harrell. The team holds a 30-17 record this season.
