Roger Federer will miss Switzerland's Davis Cup matches against
the United States and next week's tournament in Dubai as he rehabs
a back injury.
Federer said on his Web site Tuesday he did not have enough time
to completely strengthen his back after hurting it last fall. He
says he is taking a precautionary measure.
Switzerland faces the U.S. in the first round of the Davis Cup
on March 6-8 in Birmingham, Ala.
Federer says Dubai is one of his favorite tournaments, and he
regrets being unable to help his country in the Davis Cup. Federer
is ranked No. 2. He lost to Rafael Nadal in five sets at the
Australian Open final.
