Johnny Manziel: "I have to take this a lot more seriously"

Cleveland Browns quarterback Johnny Manziel has insisted that he needs to take his position a lot more "seriously".

The Browns selected the 22-year-old in the first round of the 2014 Draft, and he immediately hit the headlines for his parting antics while in Las Vegas.

Mike Pettine took the decision to make Brian Hoyer his starter for the majority of the campaign, but put Manziel into the lineup in the last two weeks, where he struggled immensely and was forced off with a hamstring injury in his side's defeat to the Carolina Panthers.

Manziel told reporters: "I have to take this a lot more seriously. It's a job for me now. I'm not the guy that I've always been. I'm not the Johnny Manziel that came in here a year ago."

The quarterback has thrown for 175 yards and two interceptions in his two games this season.
