Rams open practice window for injured WR Puka Nacua

LOS ANGELES – The Los Angeles Rams have opened the 21-day workout window for wide receiver Puka Nacua, the team announced Tuesday.

Nacua, who suffered a sprained posterior cruciate ligament in Week 1, has missed the Rams' last five games. The injury was an aggravation of a knee injury sustained in training camp.

The window gives Nacua the opportunity to practice without coming off injured reserve; He now has 21 days to be included in the squad.

The Rams have been without their top two receivers since Week 2, but expect receiver Cooper Kupp to return from an ankle sprain on Thursday night against the Minnesota Vikings.

Last season, Nacua set records for the most receptions (105) and receiving yards (1,486) by a rookie in NFL history. Nacua had four catches for 35 yards in the Rams' season opener before his injury.
