Tampa Bay Buccaneers quarterback Baker Mayfield has filed a federal lawsuit against a financial firm owned by his father, James Mayfield, accusing the company of failing to repay nearly $12 million withdrawn without his permission .

The 29-year-old NFL star filed a civil lawsuit Friday in the U.S. District Court for the Western District of Texas for $11.7 million.

The lawsuit alleges that from 2018 to 2021, Camwood Capital Management Group transferred more than $12 million from Mayfield and his wife “without his consent, proper documentation or adequate accounting of the transactions” to a subsidiary called Texas Contract Manufacturing Group.

Camwood allegedly used the money “however they saw fit,” the lawsuit says, including to finance acquisitions or to cover general corporate expenses.

“During the period that Plaintiffs’ funds were funneled to Defendants, Plaintiffs were the primary source of financing and capitalization for Defendants. In return, Plaintiffs received nothing,” the lawsuit said.

When Mayfield found out and questioned the company about it, Camwood allegedly avoided Mayfield’s questions and “created fictitious explanations for their actions,” according to the lawsuit.

Camwood did not immediately respond to a request for comment from NBC News on Tuesday.

NBC affiliate WFLA-TV of Tampa reported that Camwood is owned by James Mayfield, and that his son, Matt Mayfield – Baker Mayfield’s brother – has an interest in it.

Attempts to reach James Mayfield and Matt Mayfield were unsuccessful. They are not named as defendants, but are listed in the lawsuit as members of the company.

In January, Baker Mayfield and the company reached a settlement. Under the agreement, Camwood was required to repay $11.7 million plus interest beginning Sept. 30, the lawsuit said. The company also had to refinance an existing loan to free up capital to repay Mayfield and give him access to their books and records, the lawsuit said.

However, the lawsuit accuses Camwood of violating the settlement agreement.

“It is now clear that Defendants did not intend to make Plaintiffs cured when they entered into the settlement agreement,” the lawsuit said. “To date, Camwood Capital has not repaid a single dollar under the settlement agreement, Defendants have failed to refinance their existing loan, and Defendants have not provided Plaintiffs with access to their books and records.”

The lawsuit says Mayfield had no choice but to file a lawsuit because Camwood failed to honor the settlement agreement.
