The Memphis Grizzlies are set for another huge matchup against the Oklahoma City Thunder on Wednesday. The Thunder are the No. 1 seed in the Western Conference and defeated the Grizzlies in their last matchup while the Grizzlies were ranked No.

Jaren Jackson Jr., who left Monday's game with an ankle injury, is listed as out with an ankle sprain. He is considered week-to-week with a Grade 2 ankle sprain, the Grizzlies announced Tuesday evening.

For the slumping Memphis Grizzlies, this isn't the best time to play the best team in the NBA's Western Conference. The Grizzlies, who have suffered three straight last-second losses, host the Oklahoma City Thunder Wednesday night.
