As if the San Francisco 49ers weren't dealing with enough to begin the 2026 season, news broke earlier this week that Rams legend Aaron Donald worked out for his former team, making his coming out of retirement all but a done deal. If he does decide to rejoin Los Angeles before Week 1, San Francisco would be his first victim. Donald's return would be devastating for a 49ers team that already finds itself chasing two division frontrunners. Donald's return paired with 49ers injuries could spell disasterThe disparity in health between the 49ers and their divisional counterparts is nothing short of comical. It's difficult to see how San Francisco could pull off a division upset as it is.
