Leon Draisaitl skated by himself before the Edmonton Oilers’ morning practice Monday at Rogers Place, a sliver of good news after he was diagnosed with a concussion after the Thanksgiving loss to the Winnipeg Jets. Draisaitl, who was placed on injured reserve Monday, isn’t yet well enough to practise, even with a no-contact jersey, but Oilers head coach Todd McLellan says the first-line right-winger may travel on the upcoming road trip. “Leon won’t play against Carolina and neither will Drake Caggiula (on IR with an undisclosed problem) but both will be evaluated tomorrow (Tuesday) to see about going on the road trip,” said McLellan. The Oilers start the road trip on Thursday against the Chicago Blackhawks before dates against the Philadelphia Flyers and the defending Stanley Cup champion Pittsburgh Penguins. Draisaitl’s first-line right-wing spot with Connor McDavid now belongs to rookie Kailer Yamamoto. The Oilers also miss Drasaitl on the first power-play unit along with McDavid, Mark Letestu and Milan Lucic. Caggiula’s speed has been sorely absent from the Top 9 since he was hurt in Vancouver on Oct. 7 against the Canucks.
