Caitlin Clark will miss the Indiana Fever’s game on Thursday night against the Los Angeles Sparks as she deals with a left groin issue, the Fever announced.

Coach Stephanie White said she found out about Clark’s injury late Wednesday night, after the team’s training staff had taken Clark for an MRI.

“I think it’s very much a day-to-day thing … how she responds to treatment,” White said Thursday when asked about a possible timetable for Clark’s return.

Clark did not miss a game in college or her first year in the W, but she just over a week ago Clark returned from a left quad injury that held her out for five games.

The Fever went 2-3 without Clark between May 28 and June 10.

Since her return, she has averaged 17.8 points over five games, including a 32-point outburst in her first game back against the New York Liberty, handing the defending champions their first loss of the season. Clark hit seven 3-pointers in that game, but she’s struggled of late from distance, making just 1 of her last 23 attempts from the 3-point line in her last three games, two of which the Fever lost.

Clark also missed Indiana’s first preseason game on May 3 with a left leg issue. When Clark injured her quad, Fever coach Stephanie White said that was not related to her preseason injury. It’s unclear if this groin injury is related and if she could miss an extended period of time.

Clark is averaging 18.2 points on 39% shooting, including 29.5% from 3, 8.9 assists and 5.6 rebounds per game through her nine games this season.

After Thursday’s home matchup against the Sparks, the Fever get right back at it Friday night against the Wings in Dallas, something White says she’ll consider regarding Clark’s possible availability.

“Certainly, in my mind, it is,” White said of the tight schedule. “At the same time, she has shown she’s tough, and a quick healer, so we’ll see.”

After Friday’s game in Dallas, Indiana has five days off before hosting the Las Vegas Aces next Thursday at Gainbridge Fieldhouse.
