Tuesday marked another day on the sidelines for Los Angeles Rams quarterback Matthew Stafford, whose back problem continued to keep him out of duty at training camp.

Last month, Sean McVay said he didn't have "any reason to be concerned" about Matthew Stafford. That's no longer the case, unfortunately.

Stafford worked out on Saturday and looked good throwing 60 passes, but Coach Sean McVay says the veteran continues to feel soreness in his back.
