Dortch will suit up for his Bills debut Sunday against the Texans.
Dortch was waived by the Lions a few weeks ago, but caught on with the Bills, and was elevated from their practice squad Saturday. He had caught 24 or more passes in four consecutive seasons with the Cardinals, but his role in Buffalo currently projects to primarily be in the return game, as he presumably remains behind the likes of Keon Coleman and Joshua Palmer (and starters DJ Moore and Khalil Shakir) on the WR depth chart.
