LOS ANGELES – Rams quarterback Matthew Stafford will miss the first block of training camp – head coach Sean McVay described that as the five-day acclimation period that begins today – with back soreness, McVay announced Tuesday.

"Matthew's feeling good. He had a little bit of soreness in his back that kind of crept up," McVay said as players reported to Rams Training Camp presented by UNIFY Financial Credit Union. "He's been throwing, feeling good. It's not anything that's necessarily new, something that he's dealt with before. Going into Year 17, we were going to take a modified approach with him, kind of similar to what we did in the offseason program."

McVay said that during that five-day acclimation period, Stafford will work to the side on his own, "get himself feeling as good as possible," and then be ready for the second block of training camp, which begins after the conclusion of the acclimation period. In the meantime, Jimmy Garoppolo will step in and handle Stafford's reps with the first-team offense.

"(Stafford) feels good about that, I feel good about that," McVay said. "And ultimately, it's about having him feel as good as possible, mentally, physically, emotionally, going into Year 17."

McVay also indicated it's not something he's concerned about, and that they feel good about Stafford returning to a full practice schedule in that second block of camp.

"If he was a first-year player, then I think you'd say, 'Man, every rep really matters,'" McVay said. "I think the important thing is having a big-picture perspective with a guy going into Year 17."
