The Rams’ injury woes continued Thursday when star receiver Puka Nacua left practice because of a calf injury, a team official said.

Nacua was sidelined for two games this season because of a hip injury, but he has played the last three games for a Rams team that opened the season as the Super Bowl favorite but is 2-4 heading into Sunday’s game against the Raiders in Las Vegas.

The Rams are already thin at receiver in the wake of a hamstring injury suffered by Davante Adams during the Rams’ 18-16 defeat by the Arizona Cardinals last Sunday. Adams, 33, will be sidelined for six to 10 weeks, coach Sean McVay said.

It remains to be seen if Nacua, who led the NFL in receptions last season, will play against the Raiders.

Jordan Whittington, Konata Mumpfield, Tutu Atwell and rookie CJ Daniels are other Rams receivers.
