Nike Ends Johnny Manziel Endorsement Deal

Former Cleveland Browns quarterback Johnny Manziel has lost his endorsement deal with Nike ESPN reports.

The move from his biggest sponsor, apparently made sometime after the end of the NFL season, is the latest in an ongoing collapse of professional support for the hard-partying 23-year-old. The Browns announced they would be releasing Manziel from his contract in March and he was dropped by his agent , Drew Rosenhaus, this week "in the hopes of helping him get the treatment I believe he needs."

The termination of the Nike endorsement, which was supposed to be a multiyear deal beginning in 2014, follows other losses, including those from Nissan, McDonald's and MusclePharm.

The Huffington Post has reached out to Nike for comment.

The potential loss of Manziel's sponsorship was first reported back in January after a source told TMZ the brand was "worried " about the athlete and hoped "things will turn around in the right direction." That move followed several high-profile escapades that eventually landed Manziel in rehab .

Since he left the treatment facility, Manziel has admitted to drinking , been accused of destroying a rental house in Los Angeles and is currently under investigation by a grand jury over an alleged assault against an ex-girlfriend.
