It has been a very turbulent two years for Johnny Manziel since being drafted into the NFL in 2014 by the Cleveland Browns.
Following the firing of head coach Mike Pettine, it looks like Manziel's Browns career is now over, but could his latest controversy end his entire NFL career?
More domestic violence
Manziel has always been a controversial character, but when he was reportedly involved in domestic violence altercation with his former girlfriend, he tapped into one of the worst issues within the NFL.

Manziel reportedly threatened to murder his now ex- girlfriend Colleen Crowley and then himself during a heated argument where she claims that Manziel struck her several times.
The Cleveland quarterback as expected denied these claims, but there may be some evidence to the contrary.
Crowley's attorney has now made the claim Manziel hit his former flame with so much force that he ruptured her left ear drum.
"They expect [the ear] to heal, but it'll take a while," attorney Kathy Kinser told KXAS.
Manziel is now part of a criminal investigation for the events but it looks like there will be very few ways out for the troubled young player.
Manziel's Cleveland career is already confirmed to be coming to an end, but domestic violence is a real hot button within the NFL and could really bring an end to a very young NFL career.
From Rice to Manziel
Ray Rice is often used as the landmark example of how domestic violence can bring to an end, the careers of NFL players.
Rice was famously released by the Baltimore Ravens then suspended indefinitely by the NFL following the release of footage of him striking his now fiancee in an elevator.
Now re-instated in the NFL but never really approached by any team, he works day after day to try and secure a return to the NFL.
Dallas Cowboys defensive lineman Greg Hardy is another example of a player with a history of domestic violence and although he still plays in the league, is often heavily ostracised by fans.
Could Manziel find himself with the same treatment as Rice by the NFL when he becomes a free agent, or like Hardy, will he be welcomed by another franchise? Possibly even the same one?
