Browns quarterback Johnny Manziel has entered treatment for an unspecified condition.

An advisor for Manziel said in a statement released by the team Monday that Manziel decided to enter treatment during the offseason. Brad Beckworth says Manziel knows there are areas he needs to improve on to be a better family member, friend and teammate.

Browns general manager Ray Farmer says the team fully supports Manziel and respects his initiative in entering treatment. He says the team will respect Manziel's privacy during treatment.

Beckworth says the former Heisman Trophy winner and his family are asking for privacy until he rejoins the team in Cleveland.

Manziel has faced questions for several years about a penchant for partying, with some critics saying he's not ready to lead an NFL team.

Manziel mostly backed up Brian Hoyer last year for the Browns and struggled in two starts before getting hurt.
