Mayfield and his wife, Emily, allege a breach of contract and failure to repay millions against a collection of companies that are linked to Baker's father.

Under the contract terms, Mayfield can demand the full outstanding balance to be paid immediately, per the lawsuit.

Tampa Bay Buccaneers quarterback Baker Mayfield filed a federal lawsuit against a financial firm owned by his father, James Mayfield, accusing the company of failing to pay back nearly $12 million taken without his authorization.
