• The 49ers left Arizona with a 36-30 win, but the game never settled into the kind of clean, comfortable result that usually lets a team celebrate and move on.
  • Mike Evans was ruled out after taking a hit and later reported as dealing with a rib strain.
  • Trent Williams also left and was carted off, though his injury is not thought to be serious.
  • Evans’ exit came just before halftime, after he had already given San Francisco something to build on.
  • Brandin Cooks is the player whose role changed most sharply after that.
  • Williams did not return after suffering a stinger, and while that issue is not considered serious, it still added to the sense that the 49ers were spending the afternoon patching together answers as much as they were chasing points.
  • This was the fourth time a 49ers player had been carted to the locker room this season.
  • Even so, the 49ers did enough to win.
  • The result moved San Francisco to 3-0 and gave it a second NFC West victory, but the record now sits beside a more immediate question: how long can the 49ers keep producing this kind of offense while the roster keeps thinning around it?
  • San Francisco remains at Levi’s Stadium in Week 4 to close out its three-game homestand against the Denver Broncos, and the same players who helped survive Arizona may be asked to carry even more if Evans misses time.
  • He is expected to be evaluated Monday, and it is still unclear how long he will be out, though it could be a few weeks.
  • For now, the 49ers have the win.
