ST. PAUL, Minn. - The Rangers' stretched-thin defense could be getting Michal Rozsival back next week.

Rozsival, who was left behind on this two-game western trip for treatments on his shoulder and knee, missed his sixth game last night. But coach John Tortorella said the veteran received platelet-rich plasma therapy and is scheduled to skate today in Westchester. PRP therapy, which Marian Gaborik underwent to help speed the healing of his separated left shoulder, involves spinning a sample of a patient's blood to enrich it and then injecting it into the affected area.

Rozsival, who has two goals and six assists in 15 game, was ruled out by Tortorella for tomorrow's game against Calgary but is hopeful that he will play late next week, when the Rangers are in Florida and Nashville.

Biron starts


Martin Biron, who replaced Henrik Lundqvist in the second period in Colorado Friday, started his sixth game. Tortorella said it was a planned start and not related to his stated "concern" about his No. 1 goaltender's shaky play in his last two losses. Biron entered 3-2-0 with a .902 save percentage in six appearances. Lundqvist, who likely will start against the Flames at the Garden Monday, is 7-7-2 with a .914 save percentage.
