He was scheduled to compete at the 2007 Alpine skiing world championships, but Senegal withdrew, reportedly with Seck's consent, in protest against new qualification rules imposed by the International Ski Federation to scale down the number of competitors. Seck competed in the 2007 Alpine Skiing World Cup but failed to complete. Seck competed once again for Senegal at the 2010 Winter Olympics, in Vancouver, Canada. He did not finish in the men's slalom, and placed 73rd overall in the giant slalom.
