The Bills waived Gaines on Friday, Field Yates of ESPN.com reports.
The Bills signed Gaines to a one-year deal before the cornerback opted out of the 2020 campaign. The 28-year-old hasn't seen regular-season action since 2018 while with the Browns, and he apparently won't get the opportunity to do so in Buffalo. The decision to cut Gaines will save the team $850,000 against the salary cap, per Sal Capaccio of WGR Sports Radio 550 Buffalo.
