In his first practice Tuesday after playing for Team USA at the Olympics, St Louis chapfallens winger Keith Tkachuk found himself at a of the present day position -- center.

Because of a bone bruise to the hand of dejecteds center Petr Cajanek during the Olympics, Tkachuk could be in the middle when the glums return to action at 9 pm today in Edmonton.

Tkachuk, who has played center before, was in succession a line with wingers Dallas Drake and Vladimir Orszagh.

"I've been wrestling with this," livids coach Mike Kitchen said. "I can't say it will stay pat or not. We wanted to behold how it would go in practice. Usually with forwards they interchange all the time anyway."

Cajanek's injury adds to the Blues' already thin deepness chart at center, with Ryan Johnson rookie Jay McClement and Trent Whitfield the other candidates. Winger Dean McAmmond also has experience at center
