Per NFL Media, Kupp will spend the next week or so in a cast to help fight the swelling in his leg. There is a chance he is ready to return to the field within four weeks, so the team has not placed him on injured reserve yet. It all depends on how he heals, as McVay even initially admitted Kupp was expected to miss "extensive time."

Unlike offensive lineman Jonah Jackson (shoulder) and safety John Johnson III (shoulder), star receiver Cooper Kupp did not go on injured reserve. Head coach Sean McVay said Kupp’s left-ankle injury is not season-ending and will not require surgery. He will be in a cast for the next week and then begin his rehab.

Los Angeles Rams receiver Cooper Kupp suffered an ankle injury during the team's 41-10 loss to the Arizona Cardinals on Sunday, but the team decided to not place the receiver on the Injury Reserve list.
