9:04pm: Buffalo will move ahead with a signing. The former Vikings and Colts corner agreed to join the team Tuesday night, Garafolo reports (on Twitter). Rhodes will rejoin Frazier and help out a cornerback corps suddenly in dire need. It is a practice squad agreement.
10:09am: With plenty of injuries in their secondary, the Bills could be adding a veteran in the near future. Buffalo is hosting cornerback Xavier Rhodes on a visit, per Mike Garafolo of NFL Network (Twitter link). 
A first-round pick of the Vikings in 2013, Rhodes spent the first seven seasons of his career in Minnesota. That stretch included three Pro Bowl selections, and the 2017 campaign in which he earned First-Team All-Pro honors. Across 104 games with the Vikings, Rhodes racked up 10 interceptions and 73 pass breakups.
His time there ended on a low note, however. Despite having three years remaining on the five-year extension he had signed, the Florida State product was released in a cost-cutting move in 2020. That led him to the Colts, where he was a full-time starter and registered a pair of interceptions. Given his performance, Indianapolis signed him to another one-year deal last March, though Rhodes saw a lower snap share and took a step back in terms of coverage statistics in 2021.
In Buffalo, he would likely have the opportunity to see plenty of playing time in at least the immediate future. No. 1 corner Tre’Davious White began the season on the PUP list, meaning that he will be out for at least one more game as he continues to recover from an ACL tear. Fellow starter Dane Jackson also suffered a neck injury in Week 2, and rookie Christian Benford fractured his hand during Sunday’s loss to the Dolphins (Twitter link via Garafolo’s colleague Ian Rapoport).
Rhodes could also reunite with Bills defensive coordinator Leslie Frazier, who was the Vikings’ head coach during his rookie season. Given Buffalo’s current injury situation, a deal could see him take the field right away, and give him the opportunity to boost his free agent stock while stabilizing an important position for one of the AFC’s top contenders.
Much needed depth with starting experience.
