Hall signed a contract with the Vikings on Monday, Andrew Krammer of the Minneapolis Star Tribune reports.
Hall went undrafted out of Ball State in 2022 and initially received a chance with the Raiders, but he was not able to make their roster. However, Hall has starred in spring football the last two years, recording a combined 103 receptions for 1,117 yards and four touchdowns for the Houston franchises of the USFL and UFL, respectively. He'll likely give Minnesota some depth at receiver for the remainder of camp and also can handle return duties.
