Las Vegas Aces star A'ja Wilson has been placed in concussion protocol and is out for Friday's contest against the Dallas Wings, according to ESPN's Kendra Andrews.
Wilson suffered the injury during Wednesday's loss to the Los Angeles Sparks.
Aces head coach Becky Hammon said she hasn't had a chance to talk with the team's doctors about Wilson's status, according to Callie Fin of the Las Vegas Review-Journal.
Wilson, the reigning WNBA MVP, is averaging 20.9 points, 9.6 rebounds, four assists, 2.6 blocks, and two steals this season.
The Aces are 4-4 this season. They've lost their last two contests.
