Jon “Bones” Jones is out of the UFC 200 main event after his June blood test leading up to the fight came up positive.

Jones’ will have the opportunity to have his back-up sample tested, but it won’t be resolved in time to allow the light heavyweight to compete on Saturday.  UFC President Dana White said that Brock Lesnar versus Mark Hunt will be the new main event card.

Jones previously had a failed test in the lead up to another fight against Daniel Cormier and was suspended from the organization for cocaine abuse last year.  Michael Bisping is one possible replacement for Jones this weekend against Cormier.  The full card gets underway at 10 p.m. on Saturday.
