Gurley tweeted "thank you" messages to a number of his favorite NFL teammates and role models throughout the week.
Gurley later confirmed the allegations in an interview with NFL Network's Andrew Siciliano on Wednesday. In the NFL, he has completed his final handoff.
Gurley said when Siciliano questioned whether he was done playing professional football: "I don't think there's any question about that one."
One of the NFL's most talented backs in recent years made a shocking announcement.
One supporter said, "One of my favorite @RamsNFL players of all time, sad to see it end the way it did.""Todd, you were fantastic; Rams miss you!" said a different supporter.
A fan said, "Thank you Todd Gurley for the memories on and off the field, appreciate you, and best of luck on the next chapter of life."
