San Francisco 49ers receiver Richie James Jr. has broken his right wrist during offseason workouts and won’t be ready to return to the field until after the start of training camp.

The 49ers confirmed a report of the injury by NFL Network on Friday and said they will have a better idea of how long James will be sidelined after he reports to training camp next month. NFL Network said James is expected to miss at least two months.

James is the second receiver lost to injury this week for the defending NFC champion 49ers. No. 1 wideout Deebo Samuel underwent surgery Thursday to repair a fracture in his left foot suffered during informal player workouts in Tennessee. Samuel said he expects to be back in 10 weeks, meaning his will miss the start of training camp but should be healthy for the season opener Sept. 13.
