In a surprising turn of events, San Francisco 49ers backup running back Jordan Mason had a standout performance against the New York Jets, rushing for 147 yards and a touchdown in a 32-19 victory. However, postgame comments regarding his knowledge of being named starter raised eyebrows, as Mason claimed he was informed of his starting role on Friday, while head coach Kyle Shanahan stated that the decision was made only on Monday. This discrepancy has led to concerns about the team's adherence to NFL injury reporting rules, which require accurate and timely updates on player statuses, potentially exposing the 49ers to penalties. Mason expressed frustration during his press conference, feeling misinterpreted by the media, which he attributed to the confusion over his initial comments on McCaffrey's injury status. Meanwhile, McCaffrey was ruled out shortly before the game due to persistent calf and Achilles issues, raising questions about the team's transparency. Overall, the incident has ignited discussions about the integrity of injury reports in the league.
