It has been a long fall from grace for NFL free agent quarterback Johnny Manziel, who as a Texas A&M University freshman rocketed to fame while scrambling his way to a Heisman Trophy. Some four years later, amid myriad personal and professional setbacks, a grand jury is scheduled to hear a case Thursday against Manziel from Dallas prosecutors.

The 23-year-old stands accused of hitting his ex-girlfriend in a January incident, and a grand jury could issue a decision to indict Manziel as soon as Monday. If he's not indicted, the public could find out as soon as Thursday.

For the better part of his NFL career with the Cleveland Browns, questions about Manziel's lifestyle have abounded. There were accusations of heavy partying, then an off-season stint in rehab — followed by a public apology and a hopeful moment of turning it around before more partying rumors and allegations of violence ensued.

In recent months, Manziel's partying has seemingly continued, even as he faces serious charges and has been dropped by his team, two agents and his biggest corporate sponsor.

Detailed below in an interactive timeline is a sampling of the major controversies that have surrounded Manziel, starting from his time at Texas A&M and going up to his grand jury hearing Thursday.
