Another former Alliance of American Football defender is signing with the Vikings.

Defensive end Karter Schult, the Northern Iowa product who tried out for the Vikings during a rookie minicamp last year, is expected to sign with Minnesota on Tuesday, according to a league source.

Update: The Vikings officially announced the signing on Tuesday afternoon.

Schult, 25, had seven sacks in eight games for the Salt Lake Stallions of the now-defunct AAF, which folded this month. The Tripoli, Iowa native has had stints on the Panthers and Browns rosters since going undrafted in 2017.

Schult is the third former AAF defender signed by the Vikings this month, joining safety Derron Smith and cornerback Duke Thomas. For the past couple offseasons, general manager Rick Spielman has increased the Vikings' emphasis on undrafted free agency in May; the AAF has briefly provided another similar talent pipeline.

The Vikings will have 65 players under contract after signings of Schult and quarterback Sean Mannion, with eight picks in the upcoming NFL Draft and a 90-man roster to fill. Minnesota's undrafted free-agent crop has increased each of the past three years from 10 to 13 to 17 signings last season.
