San Francisco 49ers players Brock Purdy and George Kittle recently showcased their playful rivalry after Iowa State defeated Kittle's alma mater, Iowa, 20-19. As a result of a bet, Kittle wore Purdy's Iowa State helmet during a media session, humorously acknowledging his loss. Purdy celebrated the victory by quickly texting Kittle the score, prompting Kittle to joke about the ruined weekend. Despite their college rivalry, the duo's chemistry on the field was evident as they helped the 49ers secure a win against the New York Jets, with Purdy throwing for 231 yards and Kittle making four receptions for 40 yards. This lighthearted banter illustrates the camaraderie within the 49ers locker room, which could be pivotal for their playoff aspirations.
