Last weekend's tryouts led to two players signing with the Vikings this week.

The Vikings on Tuesday finalized signings of two defensive backs — former Rutgers cornerback Isaiah Wharton and ex-LSU cornerback Terrance Alexander — after a three-day rookie minicamp in which they were among more than 30 tryouts.

Safety Jordan Martin, who was signed last month after the Alliance of American Football league ceased operations, was waived to make room on a 90-man roster now at capacity.

Wharton (6-0, 200 pounds) is listed as a safety by the Vikings. He brings durability, having started 48 consecutive games for Rutgers after he was a two-star recruit out of Kissimmee, Fla.

Alexander (5-9, 183 pounds) is also an experienced slot defender. He spent one season at LSU, where he started five games, after graduating from Stanford with a communications degree in symbolic studies. Alexander did so well he reportedly turned down a "six-figure" salary in cyber security before transferring to play at LSU.

The Vikings also signed cornerback Kris Boyd, a seventh-round pick, to his four-year rookie contract on Sunday, the team announced. Boyd is the 10th of 12 draftees to sign his contract, leaving only top pick Garrett Bradbury and seventh-round long snapper Austin Cutting unsigned.
