Two days after being released by the New Orleans Saints, wide receiver Rishard Matthews announced his retirement from the NFL on Instagram on Monday.

In the lengthy Instagram post titled “No Longer Exist,” Matthews said in part that he was tired of feeling disposable as an NFL player. He said he won’t miss the “brainwashing” and “fakeness” he experienced during his career.

Matthews, 29, appeared in 87 games over parts of seven seasons with the Miami Dolphins (2012-15), Tennessee Titans (2016-18) and New York Jets (2018). He signed with the Saints in June. He caught 230 passes for 3,160 yards and 21 touchdowns. His best season came with the Titans in 2016 as he set career highs with 65 receptions for 945 yards and nine TDs.
