Cleveland players, coaching staff and fans appeared filled with both joy and bemusement by what had happened. 

Supporters at the at FirstEnergy Stadium in Ohio, wrapped up against the bitter Midwest winter weather, started jumping up and down with happiness when they realised their team's losing streak was finally over.

Others pumped their fists in the air while in contrast the Chargers players appear dumbfounded they lost to a team of losers.

Going into the match, the Browns were on course to become only the second team to lose all 16 games in an NFL season. 

That unwelcome record continues to be held by the 2008 Detroit Lions.
