Former Cincinnati Bearcats standout Connor Barwin announced his retirement Monday night on Instagram - on the eve of his 33rd birthday - after 10 National Football League seasons.

Barwin had a visit with the Miami Dolphins in May but did not sign with any NFL team before the start of this season. He said in June that he wanted to return to the Philadelphia Eagles, for which he started all 64 regular-season games in four seasons - including his 2014 Pro Bowl campaign that included 14.5 sacks.

Barwin's other six seasons in the league included one for the New York Giants, one for the Los Angeles Rams and his first four with the Houston Texans. He was a 2008 second-round draft pick out of UC.

Barwin and the Giants parted ways in January after the team reportedly told him he would be released before he could play the second year of the two-year contract he signed last July. The Eagles released Barwin in March of 2017.

Barwin also was among former UC basketball players to congratulate last year's Bearcats team on its AAC regular-season championship.
