Warring had a workout with the Giants early in the week, Art Stapleton of The Bergen Record reports.
Warring signed a contract with the Saints on May 24 but was waived less than a month later. He was a third-round pick in the 2019 NFL Draft, and he hasn't yet been able to make an impact at the NFL level. Warring notched three catches for 35 yards in 2020 with Houston but hasn't hauled in a pass since. He saw limited NFL time with the Bills and Jaguars last year.
