​The 2-0 San Francisco 49ers are set to host the 1-1 Arizona Cardinals for a Week 3 NFC West showdown on Sunday afternoon at Levi’s Stadium.On Thursday, the team held their second practice of the week at their SAP Performance Facility, and afterward, they released their second injury report of the week.The biggest news on the report was that defensive end Nick Bosa didn’t participate again. While he was listed as a non-participant on Wednesday, the team said he didn’t practice on Thursday due to knee and calf injuries.Hopefully the 49ers are just being extra cautious, and Bosa isn’t in danger of missing time.Joining Bosa as non-participants were wide receiver Mike Evans (hip), defensive end Romello Height (hand), wide receiver Demarcus Robinson (ankle) and defensive lineman James Thompson Jr. (ankle).Linebacker Dre Greenlaw (rest/Achilles), running back Christian McCaffrey (rest) and left tackle Trent Williams (rest) all returned to practice on Thursday and participated fully.More 49ers: 49ers head coach, offensive star explain what new WR brings to SFThis article originally appeared on Niners Wire: 49ers second injury report for Week 3 is bad news for superstar
