Armstrong formally charged

The U.S. Anti-Doping Agency filed formal charges against Lance Armstrong, accusing the seven-time Tour de France winner of using performance-enhancing drugs throughout the best years of his career.

The charges, made in a letter Thursday, came after a USADA review panel examined evidence in the case, which now goes to an arbitration panel. If found guilty, Armstrong could be stripped of the Tour de France titles he won from 1999-2005. This year's Tour begins Saturday.-- AP

NHLRangers re-sign Biron

The Rangers took care of an important bit of business by re-signing backup goaltender Martin Biron, giving the 34-year-old a two-year deal worth $2.6 million. Biron has backed up Henrik Lundqvist the last two seasons and his steady play and positive locker-room presence has allowed John Tortorella to give Lundqvist more rest during the season. The goaltender market is also in major flux as free agency begins Sunday. Devils goaltender Martin Brodeur hired an agent for the first time in well more than a decade, signaling he might be ready to move on from the financially troubled franchise.MEDIAAndrews parting ways with ESPN
