Injury-riddled 49ers remain undefeated with grueling Week 3 win vs. Cardinals

San Francisco emerged still undefeated after a taxing divisional matchup against the Arizona Cardinals on Sunday at Levi's Stadium, but they didn't escape unscathed. On this episode of "49ers Talk," co-hosts Matt Maiocco and Jennifer Lee Chan discuss how San Francisco gritted out a tough win despite losing pivotal players in key positions early in the season. The duo also break down another first-class performance from quarterback Brock Purdy, George Kittle being George Kittle, and how the defense is embodying a bend-don't-break-mentality in the face of injuries.
