49ers’ Nelson (knee) latest injury to WR corps

San Francisco 49ers wide receiver J.J. Nelson will be sidelined as long as one month with a knee injury, coach Kyle Shanahan announced Friday.

Nelson, who was signed by the 49ers two weeks ago, joins fellow wideouts Deebo Samuel (foot), Brandon Aiyuk (hamstring), Jalen Hurd (torn ACL) and Richie James (wrist) on the sideline due to injuries.

“J.J. Nelson has come in and done a really good job,” Shanahan said on KNBR’s “Murph & Mac show” on Friday morning. “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).”

The 49ers attempted to address the situation by signing former first-round pick Kevin White and fellow wide receiver River Cracraft on Thursday.

Nelson, 28, appeared in two games with the then-Oakland Raiders last season and caught four passes for 36 yards and a touchdown.

The 2015 fifth-round draft pick has 85 career receptions for 1,475 yards and 11 TDs in 58 games with the Arizona Cardinals (2015-18) and Raiders. The 49ers signed him to a one-year, $910,000 contract earlier this month.

Report: 49ers adding WRs Austin, Nelson

The San Francisco 49ers plan to sign veteran wide receivers Tavon Austin and J.J. Nelson, ESPN’s Adam Schefter reported Friday.

Pending results of their physicals, they would add much-needed depth at a position rocked by injuries to Deebo Samuel (broken left foot) and Richie James (broken right wrist). Travis Benjamin also opted out of the season due to concerns about the COVID-19 pandemic.

Austin, 30, played 14 games for the Dallas Cowboys in 2019. He had 13 catches for 177 yards and one touchdown, rushed six times for 47 yards and a score, and also returned 17 punts for 84 yards.

Drafted No. 8 overall by the then St. Louis Rams in 2013, Austin has gained 2,006 receiving yards and 1,340 rushing yards with 25 touchdowns from scrimmage in 96 games with the Rams (2013-17) and Cowboys (2018-19).

Nelson, 28, appeared in two games with the Oakland Raiders last season and caught four passes for 36 yards and a touchdown.

The 2015 fifth-round draft pick has 85 career receptions for 1,475 yards and 11 TDs in 58 games with the Arizona Cardinals (2015-18) and Raiders.
