The New England Patriots quarterback said in a Facebook post Friday that "I have made the difficult decision to no longer proceed with the legal process."
Brady's latest appeal was rejected Wednesday by the 2nd U.S. Circuit Court of Appeals. He would have had to convince the U.S. Supreme Court to take his case, and only about 1 percent of the appeals submitted to the nation's highest court are accepted.
