Jefferson (knee) was placed on injured reserve Saturday, Sarah Barshop of ESPN.com reports.
Despite insistence from head coach Sean McVay that Jefferson had not suffered a setback from what was reported to be minor offseason knee surgery, the third-year pass catcher is now set to miss at minimum the first two months of the regular season. Expect Ben Skowronek to once again see a sizable snap count behind the likes of Cooper Kupp and Allen Robinson.
