The Rams designated Kupp (hamstring) for a return to practice Wednesday.
The transaction opens up a 21-day window in which the Rams can evaluate Kupp before activating him from injured reserve and adding him to the 53-man active roster. Per Adam Grosbard of The Orange County Register, Kupp is in line to practice Wednesday, with Sarah Barshop of ESPN.com having previously reported that the Rams hope the wideout will be available this Sunday against the Eagles. Kupp's availability for the Week 5 matchup isn't guaranteed at this stage, but added context on that front should arrive once the team observes Kupp at practices Wednesday through Friday.
