The Patriots placed offensive lineman Wes Schweitzer on the reserve/retired list Tuesday.

Schweitzer, 31, signed as a free agent this offseason after prior stints with the Jets, Commanders and Falcons. Over nine seasons, he logged 62 starts in 90 regular-season game appearances. This spring, he split the top practice reps at left guard with former first-round pick Cole Strange, who took virtually all of them during the Patriots’ final minicamp practice Tuesday.

Schweitzer’s retirement dents the depth at an already questionable position for the Patriots. Over the offseason, the front office restocked one of the NFL’s worst offensive lines with right tackle Morgan Moses, center Garrett Bradbury and first-round rookie left tackle Will Campbell. But between them, the Pats’ guard depth is down to Strange, projected starting right guard Mike Onwenu, Sidy Sow, 2024 fourth-round pick Layden Robinson, Tyrese Robinson and 2024 third-round pick Caedan Wallace, a career offensive tackle. Undrafted rookie Jack Conley, a Boston College product, is also in the mix.
