The Los Angeles Rams have placed guard Jonah Jackson and safety John Johnson III on injured reserve due to shoulder injuries, but have decided against placing wide receiver Cooper Kupp on IR for now. Kupp, who sprained his ankle in a recent game against the Arizona Cardinals, is expected to miss an extended period but does not require surgery and may return sooner than the four-week IR minimum. The team is cautious with their remaining IR/designated-to-return slots, especially with other key players like Puka Nacua already on IR. Head coach Sean McVay remains hopeful for Kupp's early return, possibly around Week 7 or 8. The Rams are dealing with significant injury challenges, including multiple offensive linemen and secondary players on IR, which is impacting their overall performance this season.
