Boone to have surgery Tuesday
Anaheim team physician Dr. Lewis Yocum will operate on Boone, the Yankees' starting third baseman for the final three months of last season.
Henson, who intends to pursue a career as an NFL quarterback, agreed to terminate his contract, thus giving up the $12 million remaining on the $17 million, six-year deal he agreed to in 2001.
If no team claims Henson by Monday, he would become a baseball free agent. Because of the amount of money he is owed, no club is likely to put in a waiver claim.
Boone was hurt Jan. 16 during a pickup basketball game and might have torn his anterior cruciate ligament.
Also, the Yankees sold the contract of infielder Fernando Seguignol to the Nippon Ham Fighters of Japan's Pacific League. He was designated for assignment Jan. 12 after the Yankees signed infielder Tony Clark.
Seguignol was 1-for-7 (.143) for the Yankees last season and led the International League with a .341 average for Columbus, New York's Triple-A team. He had 28 homers and 87 RBIs and was voted the league's MVP.
