Sentinels co-founder and CEO Robert Moore sued the esports arm of Kroenke Sports & Entertainment on Thursday because of a dispute regarding a joint venture between the two parties.

Moore claims Josh Kroenke, a Kroenke Sports & Entertainment executive and heir to the Kroenke throne, failed to inform Moore of the impending purchase of Echo Fox's spot in the North American League of Legends league. ESPN reported on the $30.25 million deal July 23.

Moore and Sentinels have operated the Kroenke-owned Los Angeles Gladiators of the Overwatch League since late 2017, when Sentinels was known as Phoenix1. In the suit, Moore states he acted as the CEO of the company Kroenke Sports & Entertainment formed to hold its esports ventures, KSE Esports.

Moore's suit states that during that period as acting CEO, he and Sentinels were not compensated for various activities performed by the joint venture. He also claims to have gone out of pocket on certain expenses for the Gladiators.

Moore is seeking a majority stake — 51% — of the KSE Esports joint venture, of which he and his entity claim already to own 49%. Moore is also seeking relief for costs incurred.

Kroenke Sports & Entertainment's purchase of Echo Fox is still in progress and pending Riot Games approval. The deal is set to close in 23 days, according to reporting by ESPN.

Sentinels player Kyle "Bugha" Giersdorf won the Fortnite World Cup solo tournament July 28.
