Harrison will not play in Sunday's game against the Saints due to an illness, Tori McElhaney of theFalcons' official site reports.

Per McElhaney, Harrison, Kirk Cousins and David Onyemata all woke up Sunday morning feeling ill, but only Harrison will sit out of Sunday's regular-season finale. As such, Harrison will end the 2025 regular season with 29 tackles (20 solo), including 2.0 sacks, and two pass defenses across 10 games (four starts) while serving in a rotational role on defense and as a contributor on special teams. The 2018 third-rounder signed a one-year contract with the Falcons in October and will be an unrestricted free agent in the offseason.

Harrison posted 11 tackles (nine solo), including 1.0 sacks, and one pass defense during theFalcons' 30-27 overtime loss to the Panthers on Sunday.

Harrison led the Falcons with a season-high 11 tackles during Sunday's OT loss while playing 93 total snaps (78 on defense, 15 on special teams). He recorded a sack for a second consecutive game after getting to Bryce Young for a seven-yard loss early in the fourth quarter, which led to the Panthers punting on the very next play. Harrison has earned a larger role in the Falcons' defense after being signed off the practice squad to the active roster in late October, though his defensive snap count would take a hit if Divine Deablo (forearm) is activated from injured reserve ahead of Atlanta's Week 12 clash against New Orleans.

Harrison compiled seven total tackles (five solo), including 1.0 sacks, in Sunday's 31-25 overtime loss to the Colts.

Harrison compiled a new season high in seven stops while getting to Daniel Jones for his first sack of the season in the fourth quarter. The linebacker has now recorded 11 total tackles (seven solo), including 1.0 sacks, over three games since being signed to theFalcons' active roster Oct. 25.

TheFalcons signedHarrison from the practice squad to the active roster Saturday, Terrin Waack of the team's official site reports.

Harrison's addition to the active roster gives the Falcons additional depth at inside linebacker after Divine Deablo (forearm) was placed on injured reserve in a corresponding move. Harrison appeared in 10 regular-season games for the Colts in 2024, when he mostly played on special teams and logged two solo tackles and one forced fumble.

TheFalcons signedHarrison to a contract Saturday, Terrin Waack of the team's official site reports.

Harrison spent the last two years with the Colts while mostly serving in a special teams role, and he finished the 2024 regular season with two solo tackles and a forced fumble across 10 games. A special teams role would be Harrison's clearest path to making the Falcons' 53-man roster at the end of training camp.

Harrison was signed to theColts' 53-man roster from their practice squad Monday.

Harrison's move to the active roster comes as Indianapolis placed fellow safety Trevor Denbow (knee) on IR. The veteran will likely fill a depth role behind starters Julian Blackmon and Nick Cross but mostly contribute on special teams.

The Colts releasedHarrison on Sunday, Tom Pelissero of NFL Network reports.

After appearing in seven regular-season games for the Colts in 2023, Harrison re-signed with Indianapolis in March on a one-year deal. He was competing for a spot in the Colts' secondary, and across three preseason contests he registered eight tackles (five solo). The 2018 third-round pick will now look to join a team in need of secondary depth should he clear waivers.

Harrison has played almost exclusively as a safety duringColts' mandatory minicamp, Nate Atkins of The Indianapolis Star reports.

Harrison spent most of his time at linebacker last season (135 of his 234 defensive snaps came in the box), but he now appears to be transitioning back to safety for the 2024 season. Harrison tallied 20 total tackles, two interceptions and one sack in seven regular-season games in 2023.

Harrison re-signed with theColts on a one-year contract Wednesday, Adam Schefter of ESPN reports.

Harrison appeared in seven games for Indianapolis in 2023, notching 20 tackles (11 solo) and two interceptions, one of which he returned for a touchdown. He could be in line to compete for a starting role in 2024 if the Colts don't bring in another safety via free agency or the 2024 NFL Draft.

Harrison tallied 20 tackles (11 solo), 1.0 sacks, two passes defensed, two interceptions and one touchdown across seven regular-season games in 2023.

Harrison spent the first 11 weeks of the 2023 season on Indianapolis' practice squad, and shortly after being called up to the active roster he was asked to switch positions to middle linebacker following the release of Shaquille Leonard. Harrison is now set to hit free agency this offseason, and his ability to contribute at both safety and linebacker could help his odds of inking a new contract quickly.

Harrison had four total tackles and returned an interception for a touchdown in Sunday's loss at Cincinnati.

Harrison started at middle linebacker and played on 58 of the defense's 60 snaps. The former safety has switched positions and taken over the middle-linebacker role after Shaquille Leonard was released.

Harrison had an interception in Sunday's win over Tampa Bay but did not record a tackle.

He played on seven of the defense's 60 snaps in a linebacker role after previously working as a safety. He could help replace Shaquille Leonard, who was released, at linebacker, but he won't be used much in nickel and dime packages.

TheColts signedHarrison to their active roster Tuesday.

The 26-year-old safety had spent the entire season up to this point on the Colts' practice squad. Harrison has appeared in 67 games for the Jaguars and Browns throughout his six-year career, recording 223 total tackles, including nine tackles for loss and 5.5 sacks, while also recording 23 pass deflections. The Alabama product's signing is likely in response to Indianapolis waiving Shaquille Leonard on Tuesday.

Harrison was released by the Colts on Tuesday, Adam Schefter of ESPN reports.

Harrison signed a one-year deal with Indianapolis on Aug. 14 before getting released Tuesday. The 26-year-old played two years in Jacksonville and three in Cleveland before agreeing to terms with the Colts this offseason. Throughout his five-year career, the veteran safety has appeared in 67 games and tallied 223 tackles, 23 pass breakups and five interceptions.

Harrison is signing a one-year contract with theColts on Monday, Adam Schefter of ESPN reports.

Harrison spent the last three seasons of his career in Cleveland, ultimately seeing his role lessen in 2022, with just 246 defensive snaps in 16 contests, versus 559 in 2021, while only playing 12 games. He'll work to provide depth at strong safety for Indianapolis, as Julian Blackmon (hamstring) and Rodney Thomas (toe) continue to remain sidelined by their injuries.
