News you can't leave work without:

University of Illinois junior-to-be Jonathan Kuck will have more work at the Vancouver Olympics. That's because U.S. speedskating star Shani Davis won't be competing in all five individual races.

Davis, who became the first black athlete to win a Winter Olympics individual gold at the 2006 Turin Games, had planned to become the first American since Eric Heiden to skate in every individual event, a schedule that would have put him in races ranging from 500 to 10,000 meters.

But Guy Thibault, the high-performance director at U.S. Speedskating, told The Associated Press on Wednesday that Davis backed out of the 10,000 before a Jan. 17 deadline for final entries to be submitted to the international skating federation.  Kuck will take Davis' place.

"He basically told us he was not interested in doing the 10K anymore," Thibault said in a telephone interview from U.S. Speedskating headquarters in suburban Salt Lake City.

In an interesting twist, Kuck was added to the Olympic squad as the fourth member of team pursuit after Davis decided not to skate that event, instead opting to take Chad Hedrick's spot in the 10,000. Now, Kuck is not only replacing Davis in the team pursuit, he's also taking over for him in the 10,000. Ryan Bedford will be the other American entry in the grueling event.
