Stafford worked out on Saturday and looked good throwing 60 passes, but continues to feel soreness in his back.

McVay has repeatedly downplayed the severity of Stafford’s latest injury, claiming the quarterback could play in games if the Rams were in the regular season. McVay stepped back slightly from that stance Monday, saying: “I don’t know that. I think he still probably would be able to play it, just based on how he feels.”

Rams quarterback Matthew Stafford missed Monday's practice in an unexpected development as he continues to nurse a back injury. Los Angeles coach Sean McVay declared over the weekend that the 37-year-old signal-caller would participate in his first training camp practice on Monday.
