Colts 2026 UDFA Class: Signings, Rookie Minicamp Invites, and Hidden Gems to Watch

In this story:
The 2026 NFL Draft is over, but adding more competition to the mix is not.
The Indianapolis Colts ended up making eight draft selections after entering the weekend with seven, a class fully comprised of productive players from the two biggest conferences (SEC, Big Ten). They addressed many needs they had entering draft weekend, including doubling up at linebacker and edge rusher, arguably their two biggest needs before festivities began.
The Colts have a solid history of adding key contributors as post-draft signings, including linebacker Gary Brackett and running back Dominic Rhodes. Ironically, they've had even more success turning opposing UDFA signings into franchise players of their own, such as kicker Adam Vinatieri and center Jeff Saturday.
More recently, though, general manager Chris Ballard has earned a reputation for finding key contributors after the draft, particularly special teamers. Not only did he land franchise punter Rigoberto Sanchez, long-snapper Luke Rhodes, and kicker Spencer Shrader as UDFA signings, but he famously nabbed cornerback Kenny Moore II off waivers as a former UDFA signing to kick off his tenure as the Colts general manager.
Therefore, key contributors can be found even after the draft has wrapped up, and the Colts need to hit on as many prospects as possible if they want to right the ship in 2026.
The Colts exited draft weekend with 86 rostered players following their eight draft selections. With a 90-man limit to enter training camp, there will inevitably be some cuts to make room for the UDFA signings in question.
With that being said, let's take a look at the Colts' post-draft activity. From UDFA signings and minicamp tryout invites to an excerpt on which signing(s) have a chance to stick around for the long run, we've got all your post-draft needs in this single article.

Hidden Gems to Watch

Nolan Rucci is easily the most intriguing UDFA signing the Colts have made. He is a massive man at 6'8" and 314 pounds, and his incredible frame and arm length only add to said intrigue. General manager Chris Ballard has continued to find success with draft-and-stash offensive linemen late in the draft, and Rucci profiles as a potential next installment despite going undrafted.
