Chiefs sign defensive end Hunter Dimick

On Wednesday night, the Kansas City Chiefs signed defensive end Hunter Dimick.

Dimick, 25, signed with the Jacksonville Jaguars as an undrafted free agent out of Utah in 2017. An All-American for the Utes, Dimick was a four-year starter, compiling 148 tackles (87 solo and 42.5 for loss). Over his 39-game college career, he totaled 28.5 sacks — including 13.5 in his senior season, which led the Pac-10 in sacks. He is listed at 6 foot 3 and 268 pounds.

He spent the 2017 season on the Jaguars practice squad, where he was reported to be getting snaps as a fullback. Signed to a reserve/futures contract again the following January, he was ultimately released at the end of training camp. The Tampa Bay Buccaneers signed him to a contract this past January, but waived him April 29.

This signing wasn’t announced by the Chiefs. No one knew about it until Kansas City Star reporter Blair Kerkoff noticed his name on a roster at training camp in St. Joseph on Thursday morning.

It wasn’t immediately clear when Dimick had been signed — or even how he had been signed. As far as anyone knew, the Chiefs roster included all 90 players they are allowed at this point.

But as the morning progressed, we started figuring it out. We found that cornerback Keith Reaser — who suffered a torn Achilles tendon on July 29 — was no longer listed on the Chiefs official roster.

We had been expecting the Chiefs to make a roster move with Reaser — who is presumably out for the year — but as of Thursday morning, none had been announced. Eventually, Matt Derrick of Chiefs Digest reported that Reaser had been placed on injured reserve, and Dimick had taken his place on the roster.

We expect that we’ll be able to confirm all of this when the official NFL transactions report is released late Thursday afternoon. Since this signing caught the press corps by surprise, we could also learn more when head coach Andy Reid meets with the media after Thursday’s practice.
