Unfortunately, he went down on a worrisome hit in his first preseason game against the Chicago Bears. He was later diagnosed with a neck injury. After undergoing surgery, he's been ruled out for the rest of the year but is expected to make a full recovery.

Injury updates from the preseason matchup between the San Francisco 49ers and Las Vegas Raiders at Allegiant Stadium in Las Vegas.

Las Vegas Raiders running back Ashton Jeanty exited the preseason Week 2 game against the San Francisco 49ers on Saturday after a huge collision with a defender. Here's what we know about his status.

Multiple preseason injuries created serious questions about San Francisco’s offensive line stability and backfield depth heading into Week 1.

Right guard Dominick Puni and running back Corey Kiner sustained significant injuries in the first half of the 49ers’ preseason visit to the Raiders on Saturday.

Also, rookie tackle Connor Colby impressed while QB Brock Purdy was sharper than he was in last week’s joint practice against the Broncos.

As Las Vegas Raiders star Ashton Jeanty impressed against the San Francisco 49ers in their joint practice, he would have fans concerned during the team's preseason game on Saturday. With fans monitoring how the Raiders' running back in Jeanty will look in the preseason, he would leave the game with an arm issue.

The Raiders have a battle raging at right guard between Jackson Powers-Johnson and Alex Cappa. But Sunday that battle was put on hold due to injury.

The team reported that Puni was ruled out with a knee injury after a series of his leaving. We don’t want to speculate on what the injury is without having all of the information. However, nothing good has ever come from a player being ruled out within minutes of having a knee injury.
