Mustafa Ali may be on quite the roll in TNA Wrestling as the X-Division Champion, but he has yet to be locked into a contract with the promotion.

The former WWE Superstar made his debut for TNA in January of this year quickly after his non-compete clause with WWE had expired. At TNA No Surrender the following month, Ali won the X-Division Championship, marking his first taste of gold in a major wrestling promotion.

Mustafa Ali is yet to ink a contract with TNA Wrestling, despite his ongoing reign as X-Division Champion, Fightful Select reports. Instead, he is working on a 'per appearance' basis despite being one of the most prominently featured stars in TNA today.

In addition to his role with TNA, Ali has appeared for New Japan Pro Wrestling as well as a series of independent promotions. Fightful adds that other televised wrestling companies have maintained interest in possibly working with Mustafa.

Ali isn't the only notable star whose name has come up in discussions about TNA Wrestling contracts. Chris Sabin and Alex Shelley are set to finish with the company very soon in a huge blow to the promotion. There were "farewells said" backstage at the most recent TNA tapings.

Killer Kelly was believed to have finished up her time with TNA at the recent TNA Sacrifice tapings. It was later clarified that she is still under contract with TNA but is instead taking a break from wrestling for the time being. Her deal will not expire until 2025.

Ali will defend his title at TNA Rebellion against Jake Something. The latter earned the match by winning a 'Rebellion Referendum' six-way match on the March 21, episode of TNA Impact!

The show will take place on April 20, from the Palms Casino Resort in Paradise, Nevada. It'll be the sixth Rebellion event for TNA and will be headlined by TNA World Champion Moose defending his title against Nic Nemeth.
