Free-agent wide receiver Anquan Boldin will visit the Buffalo Bills on Monday, a source told ESPN's Dan Graziano.
Boldin remains unsigned after spending the 2016 season with the Detroit Lions. The 36-year-old caught 67 passes for 584 yards and eight touchdowns.
Buffalo lacks true depth at wide receiver outside of Sammy Watkins and second-round pick Zay Jones, so Boldin could be the piece the team has been searching for this summer.
