The Vikings are preparing for life without J.J. McCarthy.

The embattled second-year quarterback, who has really struggled so far this season, reported concussion-like symptoms on the flight home from a loss to the Packers on Sunday.

Minnesota is bringing in reinforcements in case McCarthy is unable to go on Sunday against the Seahawks.

The Vikings signed former Falcons 2022 third-round pick Desmond Ridder to its practice squad on Thursday, ESPN first reported.

The Vikings are currently set to start Max Brosmer in the event that McCarthy can’t clear concussion protocol.

Previous backup Carson Wentz is out for the season with a shoulder injury, forcing the Vikings to go to their third-string quarterback.

Ridder has not played this season, although he did appear for the Bengals during the preseason before being cut loose.

The Vikings picked up Ridder in September before being released in October as McCarthy missed time with a high-ankle sprain.

Ridder played for the Raiders last year, appearing in six games (458 passing yards, two touchdowns, two interceptions).

The Raiders did not win any of the games in which he appeared.

It is possible that Ridder gets activated from the practice squad to serve as Brosmer’s backup.

Brosmer played at the University of New Hampshire before transferring to the Golden Gophers.

The undrafted rookie has played very sparingly in the NFL, completing 5-of-8 passes for 42 yards and no touchdowns or interceptions.

The Vikings are in a bit of a quarterback crisis mode as McCarthy has not developed the way that they had hoped.

McCarthy did not play in his rookie year after suffering a torn meniscus that required surgery and a lengthy rehabilitation process.

Minnesota has since been linked to Daniel Jones, who is having a masterful season for the Colts and is on a one-year deal that could result in a bidding war between the two franchises for his services.
