Martavis Bryant is hoping to make a return to the gridiron.
The 27-year-old receiver, who last played with the Raiders, submitted a request for reinstatement to the NFL, ESPN's Dan Graziano reported, citing league sources.
Bryant was suspended indefinitely by the NFL in December after repeatedly violating the NFL's substance-abuse policy.
The Clemson product and his attorney were able to delay the suspension by arguing the NFL didn't address Bryant's mental health and ADHD. Bryant was diagnosed with ADHD as a child. The league ultimately denied his appeal and suspended Bryant for the third time in four seasons.
Bryant and the NFL have worked since the end of last season to address the receiver's mental health and he has been submitting to drug tests regularly, Graziano reports.
