Amelie Lacoste and Kevin Reynolds have been added as replacements to the Canadian team for the rescheduled ISU World Figure Skating Championships in Moscow.

Lacoste, from Delson, Que., will replace Myriane Samson as Canada's second entry in the women's competition behind national champion Cynthia Phaneuf.

Lacoste placed third behind those other women at this year's Canadian championships.

"Myriane has been struggling with [a knee] injury since she competed at the ISU Four Continents in February, and while she hoped to be ready to compete, it just wasn't going to be possible," Skate Canada high performance director Mike Slipchuk said in a statement released Tuesday.

"Amelie has been training well, and we know she is ready to step into the world championships with confidence."

Reynolds, from Coquitlam, B.C., will join four-time Canadian champion Patrick Chan and Joey Russell in the men's event. Reynolds replaces national silver medallist Shawn Sawyer, who has decided to tour with Stars on Ice this spring.

"Shawn's decision was a difficult one for him," said Slipchuk. "His plans were obviously affected by the delay in the timing of the worlds competition this year. We totally respect his decision to skate on the tour, and wish him well."

The world championship were originally set to be held in Tokyo from March 21-27, but after the earthquake in Japan the event was moved to Moscow, April 25-May 1.
