Thunder guard Shai Gilgeous-Alexander is out with plantar fasciitis in his right foot, coach Mark Daigneault said on Wednesday.

Daigneault added that there is no set timetable for his return.

“I don’t want to use long term because it’s vague, but it’s not day-to-day,” Daigneault said. “It’s going to be a more significant amount of time than day-to-day. This one is now an injury that we need to take a look at.”

Gilgeous-Alexander, the 22-year-old from Hamilton, Ont., leads Oklahoma City with 23.7 points per game over 35 games this season. The third-year player is also averaging 5.9 assists and 4.7 rebounds per contest for the 19-24 team.

The injury is also potentially a blow to the Canadian men’s national team, which begins its last-chance Olympic qualifying tournament June 29 in Victoria.

Gilgeous-Alexander, on a Thunder team not currently in playoff position, was expected to play a key role for Team Canada during the qualifier that runs concurrent to the NBA playoffs.

However, the injury puts Gilgeous-Alexander’s availability into question.
