The Cleveland Indians were all set to become the Cleveland Guardians starting next season, but now they're running into some legal trouble because of the name change. The Cleveland Guardians roller derby team has filed a federal lawsuit against the baseball team to block them from the name change, according to WKYC.

The Indians officially unveiled their rebranding back in July and claimed awareness of the roller derby team. But the roller derby team is now claiming they're getting stiffed in this whole situation:

The derby team’s lawsuit suggests the move was meant to surprise the derby team.

“When the roller derby team complained to the Indians, the MLB franchise offered a truly nominal amount to buy the team’s intellectual property rights, including its social media accounts and the valuable www.clevelandguardians.com domain name,” Pardo said in a statement.

Gary Sweatt, the owner of the roller derby team, said in a statement the ball club “forced us into having to protect the name we have used for years.”

The lawsuit claims the roller derby team earned “common law” trademark rights and that the Indians “surreptitiously” filed a trademark application instead of contacting the roller derby team. The baseball club finally reached out about the name to discuss purchasing the intellectual property, but the offer to the roller derby team was very small. A counteroffer was made, but that was allegedly ignored. This lawsuit also claims that the Indians lied about knowledge of the roller derby team's use of the Guardians name.

Assuming the Indians want to go through with the Guardians name change, the roller derby team just wants its fair share in a buyout of the rights to the intellectual property. There was a deadline on Tuesday for a proposal, but it passed, resulting in this lawsuit being filed against the baseball team.
