University of Kentucky signee Isaiah Briscoe will be unable to continue with the Team USA U19 squad after suffering a concussion during Thursday's practice, USA Basketball announced Friday morning.
Virginia Tech guard Justin Bibbs will replace Briscoe on the team, which will compete at the FIBA world championships in Greece later this month.
"I feel very bad for Isaiah. He had a tremendous attitude and was one of our overall best players and one of our leaders of the team," said USA U19 head coach Sean Miller of Arizona. "It is very, very unfortunate to see him get injured in what was really a two-on-two drill. But the good news is I know he'll recover and be fine; the bad news is he won't be able to play on our team."
Briscoe is expected to join his future teammates at UK soon.
The Team USA U19 squad also includes top UK recruiting targets Harry Giles, Josh Jackson and Jayson Tatum.
