A revitalized Christian McCaffrey took the ball on the 49ers’ opening play and was off and running in a heavy workload Thursday in a joint practice at the Las Vegas Raiders’ facility.

The 49ers bottled up Raiders running back Ashton Jeanty for the most part Thursday, similar to what Seattle did in a preseason game a week earlier in holding him to minus-1 yard on three carries. But Jeanty still provided a reminder in the joint practice of why he was drafted sixth overall this year by Las Vegas.

There were several rivalries renewed Thursday at the Raiders joint practice with the 49ers. Including several players, coaches, and the team itself.
