LOS ANGELES -- The Rams have designated wide receiver Cooper Kupp to return to practice, starting his 21-day practice window, the team announced Wednesday.
Kupp has been on injured reserve with a hamstring injury since the start of the season, missing the Rams' first four games. With the designation, the Rams start Kupp's 21-day window for his potential activation from injured reserve.
Kupp is expected to practice Wednesday.
Kupp first injured his hamstring during a training camp practice on Aug. 1. He then experienced a setback before the start of the season.
