Mims is expected to be sidelined several weeks due to a strained pectoral muscle, Ben Baby of ESPN reports.
Bengals head coach Zac Taylor said that Mims' injury won't require surgery, but the rookie lineman is expected to miss Cincinnati's final two preseason contests and is a question mark for Week 1 of the regular season. Mims was selected with the 18th overall pick in April's NFL Draft and had been working with the first-team offense during training camp. He presumably suffered the pec injury during the Bengals' preseason opener Saturday versus Tampa Bay, during which he logged 15 offensive snaps.
