The 2001 Clemson-South Carolina Game
20 - 15 South Carolina
In the 200th year of the University of South Carolina, the Gamecocks hosted the Tigers at the end of a successful regular season that saw them ranked in the Top 25 every week and 7–3 heading into the rivalry game. Carolina jumped out to an early 20–9 lead behind a strong ground attack, and held on to win 20–15 and secure a bid to their second straight Outback Bowl. Because of the September 11 attacks, this was not the final regular season game for Clemson. The Tigers rescheduled their September 15 game (vs. Duke) for the first weekend of December.
