There were some notable changes for both the Raiders and the 49ers on their Thursday injury reports. Both teams losing a player and getting a player back at practice.

The 49ers were looking pretty banged up on Wednesday, but Thursday they got some good news with the return ofRB Christian McCaffrey (hamstring)

But they also saw WR Christian Kirk miss practice with a knee injury. Becoming the third of their top receivers not at practice, joining Mike Evans (ribs/achilles), and Deebo Samuel (hamstring).

The Raiders got their one player who was missing back at practice. CB Darien Porter was limited after missing Wednesday with the groin injury he suffered early in Sunday's game against the Jets.

Newly out was DT Thomas Booker who suffered an ankle injury. Also newly injured was WR Donte' Thornton who was limited with a back injury.

Obviously those receiver injuries loom large for the 49ers, so it will be something to watch on Friday's injury report.
