As of my last knowledge update in September 2021, Aaron Rodgers was still with the Green Bay Packers, and I have no information about such an injury occurring. Please note that my information is not up to date, and I cannot provide real-time sports news or events that have occurred after my last update.

However, I can provide information on the injuries of Joe Theismann and Sterling Sharpe as described in your message:

1. **Joe Theismann:** Joe Theismann’s career-ending injury occurred on November 18, 1985, while he was playing for the Washington Redskins. During a game against the New York Giants, Lawrence Taylor tackled Theismann, resulting in a compound fracture of Theismann’s right leg (tibia and fibula). This injury is indeed one of the most memorable and graphic injuries in NFL history.

2. **Sterling Sharpe:** Sterling Sharpe’s career was cut short due to a neck injury in the 1994 season. Sharpe was playing for the Green Bay Packers when he suffered a neck injury while blocking Brad Edwards during a game against the Atlanta Falcons. The injury affected the first and second cervical vertebrae in his neck, and it forced him to retire prematurely, leaving many to wonder what could have been for his Hall of Fame career.
