The Vikings released Vallejo on Sunday, Tom Pelissero of NFL Network reports.

EDGE Analysis

Vallejo signed with the Vikings on Aug. 13. He spent the last four seasons with the Cardinals where he registered 81 tackles (52 solo), 1.5 sacks and two forced fumbles in 45 games. The 2017 sixth-round pick out of Boise State should gather some interest from a team looking for a veteran linebacker. He'll be able to explore his options once he clears waivers.

The Cardinals activated Vallejo (illness) from the reserve/COVID-19 list Monday.

EDGE Analysis

Vallejo can now return to team facilities and begin preparing for Monday's playoff matchup against the Rams. He projects to handle his usual role on special teams, while also providing depth at linebacker.

Vallejo was placed on the reserve/COVID-19 list Tuesday, Darren Urban of the Cardinals' official site reports. This was the result of testing positive for the virus, according to Ian Rapoport of NFL Network.

EDGE Analysis

Vallejo returned Sunday against Dallas after a six-week absence due to a knee injury. Now Vallejo is in danger of missing the Cardinals' Week 18 matchup with the Seahawks. When healthy he has provided depth at linebacker and work on special teams, roles which he'll work to return to, if he can clear protocols in time.

Vallejo (knee) has been activated from the Injured Reserve/Designated for return list Saturday.

EDGE Analysis

Vallejo hasn't played since Week 10 and the injury couldn't have come at a worse time for him, as he was starting to earn a bigger role on defense. He should be available for Arizona's final two games of the regular season, but it remains to be seen what kind of role he'll have.

Vallejo (knee) was designated to return from injured reserve Wednesday.

EDGE Analysis

Vallejo had been on injured reserve since Nov. 20, but he'll be eligible to participate in Wednesday's practice. Whether he's available for the final two games of the regular season remains to be seen, but he appears to be trending toward a return.

Vallejo (knee) was put on injured reserve Saturday.

EDGE Analysis

Vallejo had already been ruled out of Week 11 but now gets several weeks to fully recover. Joe Walker and Tahir Whitehead both joined the active roster Saturday and could absorb the 26-year-old's vacated snaps.

Vallejo (knee) is out for Sunday's game against the Seahawks, according to Darren Urban of the Cardinals' official site.

EDGE Analysis

Vallejo didn't play in Week 6 against Cleveland but logged at least 35 percent of the snaps in each of his last three games. However, he's been ruled out against the Seahawks and will miss his second game of the campaign. The former Boise State standout has not played more than 50 percent of the snaps in any single contest, though, so his absence shouldn't affect Arizona's defensive plan considerably.

Vallejo (hand) recorded a full practice Wednesday and is expected to be available for the Cardinals' Week 8 contest with the Packers on Thursday, Josh Weinfuss of ESPN.com reports.

EDGE Analysis

Vallejo was forced to miss the Cardinals' Week 6 game with the Browns as his hand injury was just starting to bother him. The linebacker managed to play in Week 7 against the Texans as he recorded a season-high number of defensive snaps (10). Expect Vallejo to be able to play against the Packers on Thursday night.

Vallejo (hand) is listed as questionable for Sunday's contest against the Texans.

EDGE Analysis

Vallejo missed Week 6 with the hand injury and was a limited participant during every practice this week. The 26-year-old linebacker has played mainly on special teams this year, so if he is unable to suit up Sunday it shouldn't have an effect on Arizona's defensive rotations.

Vallejo (hand) has been ruled out for Sunday's game against the Browns, Darren Urban of the Cardinals' official site reports.

EDGE Analysis

Vallejo has played mainly on special teams this year, but he apparently sustained a hand injury in Sunday's win over the 49ers. He was unable to practice this week, and his absence for Sunday's Week 6 matchup shouldn't have a significant impact on the team's defensive plans.
