Colts TE Jack Doyle announced his retirement on Monday. The 31-year-old turned in top-14 fantasy seasons in 2016 and 2017 but hasn't been much of a factor since. With TE Mo Alie-Cox set to hit the free-agent market, 2021 4th-rounder Kylen Granson is currently atop the Colts' TE depth chart. We'll see what else the teams adds at the position, but Granson is an intriguing late-round flier in fantasy drafts right now.
