San Francisco 49ers head coach Kyle Shanahan told reporters that wide receiver Jauan Jennings left Sunday's practice with what appeared to be a calf injury—the same issue he dealt with during organized team activities (OTAs) earlier this offseason.
"That's what he had in OTAs, so I'm sure it's similar," Shanahan said following practice.
Despite expressing frustration over his contract situation, Jennings had been a full participant throughout training camp prior to the injury. The veteran receiver is entering the final year of the two-year deal he signed in 2024 and is seeking a new agreement.
Jacob Cowing and Renard Green updates
The coach also provided injury updates on two key players, cornerback Renardo Green and wide receiver Jacob Cowing, both of whom are dealing with hamstring issues. Shanahan expects both players to return the week of August 11, when the 49ers will hold joint practices with the Las Vegas Raiders.
"Hopefully, around Raiders week, we'll get them back," Shanahan said.
Green suffered his injury during Friday's practice and was noticeably absent from Sunday's session. The setback came just two days after Cowing sustained a hamstring injury during the team's first training camp practice.
Green, entering his second NFL season, played in all 17 games as a rookie in 2024, including seven starts. He recorded 61 tackles, one interception, and 13 passes defensed, quickly emerging as one of San Francisco's most promising young defensive backs.
A second-round pick out of Florida State in the 2024 NFL Draft, Green is projected to be a key starter in 2025 following Charvarius Ward's departure to the Indianapolis Colts.
Cowing, also heading into his second NFL season, was one of the standouts during the 49ers' offseason program. He appeared in 15 games as a rookie, finishing with four receptions for 80 yards.
Scary moment during practice
There was a frightening moment during practice when defensive lineman Tarron Jackson went down during team drills and had to be carted off the field on a backboard. He was transported to Stanford Hospital for further evaluation.
Shanahan provided a positive update, noting that Jackson is conscious, able to communicate, and can feel all his extremities.
"We were close to him, so we could hear him talking," Shanahan said. "We could see everything moving. So, I just told the guys that, which I think eases them up a little bit for the biggest fears."
