Mike Garafolo of NFL Media reports that the Bills are hosting veteran LB Andrew Gachkar for a visit on Tuesday.
Gachkar visited with the Patriots a few weeks ago but left New England without a deal.
Gachkar, 28, is a former seventh-round pick of the Chargers back in 2011. He played out his four-year, $2,085,900 rookie contract with the Chargers before signing a two-year deal with the Cowboys back in March of 2015.
Gachkar finished out that contract and has been testing the open market as an unrestricted free agent but this is the first reported interest in him since free agency got underway a few months ago.
In 2016, Gachkar appeared in all 16 games for the Cowboys and recorded 10 tackles and no sacks or interceptions.
