The Bengals worked out free agent tight end Clive Walford, a source tells Ian Rapoport of NFL.com (on Twitter). If signed, Walford could help to fill the void following Tyler Eifert‘s season-ending injury. 
The Raiders made Walford an early third round pick in 2015, but he never lived up to his potential at the pro level. He received a lot of hype his first couple training camps, and was expected at various points to start at tight end for the Raiders, but ended up lasting just three years in Oakland.
The Raiders cut him back in March, and he was quickly scooped up by the Jets, who claimed him off waivers. Walford missed the Jets’ final cut, and the fact that Walford couldn’t make the Jets despite the team having very few proven options at tight end wasn’t a great look. Since then, he has auditioned for the Seahawks, Chiefs, and Jaguars, but has yet to find an NFL home for the 2018 season.
Through three seasons in Oakland, Walford amassed 768 yards and six touchdowns on 70 catches.
