Jackson (concussion) was released by the Colts on Thursday.

EDGE Analysis

Jackson had a nice season for the Colts before being suspended for its final four games due to a violation of the NFL's performance enhancing substances policy, racking up 78 combined tackles, one sack and two forced fumbles. The veteran inside linebacker would have been owed $5.5 million of non-guaranteed money in 2017 had the Colts kept him, so it is not necessarily surprising to see him released, especially taking the recent suspension into consideration. Jackson is now entering his eleventh season, but still appears to have plenty of gas left in the tank and should find himself on an NFL roster come September.

Jackson (concussion) has been suspended for four games by the NFL for violating the NFL's policy on performance enhancing substances, Zak Keefer of the Indianapolis Star reports.

EDGE Analysis

Jackson's suspension is a big blow as he's one of Indy's best players on a defense that's struggled at the linebacker position. He'll miss the rest of the regular season but could return for the playoffs. He's currently in the concussion protocol, so he'll have four weeks to recover from that injury if the Colts make the postseason.

Jackson suffered a concussion in Monday's game against the Jets, Kevin Bowen of Colts.com reports.

EDGE Analysis

Jackson managed to make four tackles prior to his premature exit. It remains unclear if he even has a shot of playing in Sunday's game against the Texans.

Jackson had nine total tackles, a sack and a defended a pass in Sunday's win over Tennessee.

EDGE Analysis

After a slow start to the season where he averaged just 5.3 takles per game over his first four games, Jackson is averaging 7.6 tackles over his last six games. However, that's still a decline from the 9.3 tackles per game he averaged last season.

Jackson had nine tackles Sunday against the Titans.

EDGE Analysis

Jackson's now registered nine tackles in two of his last three matchups, and he's averaging 7.5 stops over his last four contests. The veteran has posted at least 140 tackles in four of his last five seasons, and although he's far off that pace through seven games this year, he's certainly someone who can string together a number of double-digit tackle games before the year ends.

Jackson had nine total tackles, a tackle for a loss and recovered a fumble in Sunday's win over Chicago.

EDGE Analysis

After a slow start with just eight tackles the first two games, Jackson's tackle totals are starting to increase. It's no coincidence the increase comes as Indy's secondary returns to full health, forcing opponents to attack the middle of the field more frequently.

Jackson had four tackles, a tackle for a loss and defended a pass in Sunday's loss at Denver.

EDGE Analysis

Jackson improved his tackle totals after making just two in Week 2, but he's still far off his career averages. He's likely been involved in fewer plays with the opposing defense focusing on throwing deep amid Indy's injury-depleted secondary.

Jackson had just two tackles in Sundays loss to Detroit.

EDGE Analysis

Jackson should put up better tackle totals, but he may have been involved in fewer plays with the opposing defense focusing on throwing deep amid Indy's injury-depleted secondary.

Jackson (quadriceps) is active Sunday against the Jaguars.

EDGE Analysis

After putting in limited practices Wednesday and Thursday, he was held out of practice Friday, yet will be in the lineup at inside linebacker. After racking up 11 tackles in each of the last two games, he'll be needed to slow down TJ Yeldon and the Jaguars rushing attack.

Jackson (quad) has been listed as a game-time decision for Sunday's game against the Jaguars, Kevin Bowen of Colts.com reports.

EDGE Analysis

Jackson missed practice on Wednesday and Friday due to a quad injury, but was a limited participant on Thursday. If he is held out, it'll be a sizable loss for the Colts' defense as he leads the team with 122 tackles along with two sacks, a forced fumble, and an interception. If he isn't able to play Sunday, look for Sio Moore to grab the start.
