A federal appeals court on Thursday rejected a former DraftKings executive’s bid to overturn an injunction that severely restricts the type of work he can do now that he has joined its sports betting rival Fanatics.

The Boston-based 1st U.S. Circuit Court of Appeals rejected Michael Hermalyn’s bid to have California law applied to the dispute over his non-compete agreement with DraftKings, which would have rendered it unenforceable, and instead held Massachusetts law governed.
