The Arizona Cardinals’ bad injury situation got worse on Wednesday when starting left tackle D.J. Humphries was placed on injured reserve with a knee injury.

The move leaves rookie center Mason Cole as the only remaining member of the offensive line that began the season, and he took over late in the preseason when starter A.Q. Shipley went down with a season-ending knee injury. Guards Mike Iupati and Justin Pugh are on injured reserve and tackle Andre Smith was released.

Earlier this week, rookie Christian Kirk went on IR with a broken foot, depleting an already thin wide receiver group.

Humphries is the 14th Cardinal, and sixth offensive lineman, to go on injured reserve.
