The NBA's summer leagues get started Saturday in Orlando, but it's a matchup the following day that could be the most intriguing for University of Kentucky fans.
The Harrison twins, both trying to make a case for a roster spot on their respective teams, will square off at 3 p.m. Sunday in a game televised on NBA TV. Andrew, a second-round pick, will play for the Memphis Grizzlies. Aaron, who went undrafted, is on the Charlotte Hornets' squad.
There are three summer leagues this year, and the rosters are loaded with former UK stars. Fourteen ex-Cats and 12 others with Kentucky ties are expected to play, though not all rosters are official and rookies will need to sign their contracts before participating.
Other highlights this summer will include No. 1 draft picks Karl-Anthony Towns and Andrew Wiggins teaming up for the Timberwolves in Las Vegas. Julius Randle will return to action for the first time since suffering a season-ending leg injury in his NBA debut last season for the Lakers. Darius Miller, part of a league championship in Germany recently, will try to earn his way back to the NBA with the Mavericks.
Never miss a local story.
