Both players were set to compete for roles in Indianapolis’ secondary this year. They join Colts LB Skai Moore to give the team three players opting out in 2020.
Tell, 24, was drafted by the Colts in the fifth round out of USC in 2019. He signed a four-year, $2.848 million rookie deal and was set to make a base salary of $675,000 in 2020.
In 2019, Tell appeared in 13 games for the Colts and recorded 26 total tackles, one forced fumble and five pass defenses.
Milligan, 26, wound up signing with the Cowboys as an undrafted free agent out of Toledo in 2016. He was waived from their injured reserve with a settlement and signed with the Lions during the 2017 offseason.
Milligan was on and off of the Lions’ practice squad before the Colts later added him to their taxi squad in October of 2018. He re-signed on a futures deal for 2019 and joined the practice squad after being waived at the end of the preseason.
The Colts promoted him to their active roster in September of last year but was placed on season-ending injured reserve in December. He re-signed as an exclusive rights free agent this offseason.
In 2019, Milligan appeared in 11 games and recorded 13 total tackles with no sacks or interceptions.
