Tom Heckert has passed away at the age of 51.

Heckert spent the last five years in the Broncos’ personnel department, helping the team to three playoff appearances (2013-15), two AFC Championship Game wins (2013 and ’15) and a victory in Super Bowl 50 (’15). He worked as the Broncos’ Director of Pro Personnel from 2013-16 before accepting a position as the team’s Senior Personnel Advisor in 2017.

Heckert was general manager of the Cleveland Browns from 2010 until 2012, and the Philadelphia Eagles from 2006 until 2009.

Heckert stepped away from the Broncos following the 2017 season to focus on his health, having been diagnosed in recent years with amyloidosis.
