The OKC Thunder will be without both of its big men on Thursday against the East-leading Cleveland Cavaliers.

The team confirmed that center Isaiah Hartenstein strained his left calf in Tuesday's game against the Philadelphia 76ers.

The Thunder said he will be re-evaluated in one week, which means he will miss the much-anticipated rematch with the Cavaliers in Oklahoma City.

In last's week's matchup, Hartenstein played 31 minutes and had 18 points, 8 assists and 11 rebounds. The Thunder lost a close one, 129-122.

OKC's star center and former No. 2 overall pick Chet Holmgren has been out for over two months with a hip injury.

The loss ended OKC's franchise-record winning streak.
