Johnny Manziel hasn't given up on playing football in the NFL this season.

However, a source close to the quarterback says he recognizes that window might be closing, making a possible 2017 comeback attempt more feasible.

"His immediate plans are to start getting ready for football," said Manziel's attorney Jim Darnell. "We're working on it."

Since being released by the Cleveland Browns in March, Manziel has been charged with misdemeanor assault charge for allegedly rupturing the eardrum of ex-girlfriend Colleen Crowley in a January dispute, sued over a trashed rental home and dropped by two agents, Erik Burkhardt and Drew Rosenhaus.
