The San Francisco 49ers will be without receiver/returner Ray-Ray McCloud for about two months after he broke his left wrist, coach Kyle Shanahan said Thursday.

McCloud injured the wrist while trying to haul in a deep pass from quarterback Sam Darnold in Tuesday's practice and is slated to have surgery Friday. He is expected to miss eight weeks.

"They always say around eight weeks," Shanahan told reporters after Thursday's practice with the Las Vegas Raiders. "It could be a little less. Hopefully, it is. We'll see.
