Nelson likely out a month as 49ers' receiver injuries mount

San Francisco 49ers

The injury bug again has bitten the 49ers' receiving corps.

After signing with the 49ers early in training camp, J.J. Nelson went down with a knee injury this week in practice, and coach Kyle Shanahan told KNBR on Friday morning that the wide receiver will be out for the foreseeable future.

“J.J. Nelson has come in and done a really good job," Shanahan said on the “Murph & Mac show.” "He's been banged up the last two days. We just got some injury stuff on him yesterday, so he's going to probably be out here for the next month, so you lose another [receiver]."

Nelson joins Deebo Samuel, Brandon Aiyuk, Richie James and Jalen Hurd as 49ers receivers on the shelf, as injuries continue to mount at the position.

ESPN’s Adam Schefter reported after Shanahan's appearance that Nelson will miss 2 to 4 weeks, roughly matching up with the coach's estimated timeline.

One month from now would put Nelson's potential return somewhere around the 49ers’ Week 3 game on Sept. 27 in New York against the Giants. The 49ers will play in New York on back-to-back weeks after the home opener in Week 1, so anyone who isn’t ready for Week 2 could miss both of those games as the 49ers likely will stay on the East Coast instead of doing another series of cross-country flights in a short span.

Kevin White and River Cracraft officially were signed Thursday as the 49ers try to keep healthy bodies out there in training camp, but Nelson's injury is another in what has been a series of issues plaguing the organization at an important position.
