Leary recently suffered a season-ending torn Achilles, so this move was expected.
Leary, 29, wound up signing on with the Cowboys as an undrafted free agent out of back in 2012. He played out his rookie contract with the Cowboys before signing a four-year, $36 million contract that included $18.65 million guaranteed with the Broncos last year.
Leary stands to make a base salary of $7.65 million for the 2018 season.
In 2018, Leary appeared in six games for the Broncos.
