Stafford, 37, has not practiced since the Rams opened training camp while receiving treatment from trainers and the team medical staff for what McVay initially described as back soreness. McVay said last Tuesday that Stafford would sit out the first block of practices, but return on Monday when the Rams will be in pads for the first time.

The veteran quarterback will not participate in next week's workouts, and it's unknown when he'll return to action.

Pro Bowl quarterback Matthew Stafford was expected to miss the first handful of practices with a sore back, but head coach Sean McVay gave an update on Stafford's status on Saturday that likely has Rams fans at least a little concerned.
