Mayo captioned the post, “Retiring a Patriot.”
Mayo, 29, finished last season on injured reserve for the third straight year after sustaining an injury during the Patriots’ win over the Chiefs in the divisional round of the playoffs. Mayo was due over $10 million in base salary and bonuses in 2016.
The Patriots selected Mayo No. 10 overall in the 2008 NFL draft. He played a key role for the team during his first five seasons, before injuries limited him to 12 games combined in 2013 and 2014. Mayo’s health was better last season, but he spent significantly less time on the field, often coming off for third down plays.
In his career, Mayo played 103 games, with 803 combined tackles, eight forced fumbles and three interceptions.
