Oklahoma City Thunder guard Shai Gilgeous-Alexander is expected to miss a "significant amount of time" with plantar fasciitis in his right foot, according to coach Mark Daigneault.
Gilgeous-Alexander was added to the injury report on Wednesday, and he did not suit up for Oklahoma City's 116-107 loss to the visiting Memphis Grizzlies.
"I think he walked in this morning and that's when we started to kinda unpack it," Daigneault said of the injury. "I don't have a ton of detail on it to be honest with you. It happened pretty quickly today."
Daigneault said there is no set timetable for Gilgeous-Alexander's return -- only that it's "not day-to-day; it's going to be a more significant amount of time."
The coach indicated the injury didn't happen on a particular play and in all likelihood is "a little bit more cumulative" from the wear and tear of the condensed season.
Gilgeous-Alexander, who leads Oklahoma City with 23.7 points per game, is averaging a team-high 34 minutes.
"Like I said, he's a higher-minute player that's tracked a lot of miles so far this season after a short offseason," Daigneault said.
At 19-25, the Thunder are 12th in the Western Conference standings.
