Nickerson (concussion) was placed on injured reserve Saturday, Brooks Kubena of the Houston Chronicle reports.

EDGE Analysis

Nickerson had already been ruled out for Sunday's game against Tennessee, but he'll now be forced to miss at least three contests. However, the linebacker's absence shouldn't impact Houston's defensive plans.

Nickerson (concussion) has been ruled out of Sunday's game against Tennessee.

EDGE Analysis

This means Nickerson will have to wait to make his third appearance of the season after seeing the field previously in Week 4 and Week 8. He's played only nine defensive snaps this season, though, so his absence shouldn't have a major impact on Houston's game plan this weekend.

Nickerson (concussion) will not play Sunday against the Dolphins.

EDGE Analysis

Nickerson was just bumped up from the practice squad Thursday, but he won't be cleared in time to play Sunday. Nickerson spent time on the active roster earlier this season, appearing in the Texans' Week 4 and Week 8 games against the Bills and Rams, respectively.

Nickerson (concussion) was promoted to the Texans' active roster from the practice squad Wednesday.

EDGE Analysis

Nickerson failed to make Houston's initial 53-man roster but stuck around the team on the practice squad and will now join the active roster. The 27-year-old has appeared in two contests as a gameday elevation and primarily played special teams.

The Texans signed Nickerson to a contract Monday.

EDGE Analysis

Nickerson logged 14 tackles in as many games for the Vikings last season, in addition to one pass breakup, one interception and two forced fumbles. He'll contribute as a special-teams asset and depth linebacker with Houston.

The Vikings signed Nickerson to the active roster Saturday.

EDGE Analysis

The Vikings cut Nickerson on Dec. 1 after he played nine games for the team. In that stretch, Nickerson rarely played on defense and finished with just six tackles. He's back with the Vikings, however, and he'll add depth at middle linebacker with Eric Kendricks (calf) ruled out for Sunday's game against the Buccaneers.

Nickerson had one total tackle and played 36 of the defense's 75 snaps in Sunday's loss to Tennessee.

EDGE Analysis

Nickerson moved into a role as the No. 3 linebacker after Anthony Barr suffered a season-ending pectoral injury. However, his increase in playing time may not last long as Todd Davis may overtake him on the depth chart once he gets up to speed after signing with the Vikings just before Week 3.

Nickerson signed with the Vikings' active roster Tuesday.

EDGE Analysis

Anthony Barr suffered a torn pectoral muscle this past Sunday and has been ruled out for the year, so Nickerson could play an immediate role for the Vikings. However, Troy Dye and Ryan Connelly are in line for the starting gig that Barr left behind.

Nickerson was promoted to the Vikings' active roster Saturday, Chad Graff of The Athletic reports.

EDGE Analysis

Nickerson failed to secure a spot on the team's initial 53-man roster, but the new practice squad rules allow two players to get activated in each game. There's a good chance he makes his Vikings debut as a result, working as one of the team's top reserve linebackers.

The Vikings signed Nickerson on Tuesday, Aaron Wilson of the Houston Chronicle reports.

EDGE Analysis

Nickerson's chance to compete for a reserve role comes following Minnesota's move to place Quentin Poling (undisclosed) on injured reserve. The 26-year-old played a reserve role in Cincinnati for stints during the last three seasons.
