The Edmonton Oilers offence is about to get a boost as forwards Leon Draisaitl and Drake Caggiula will re-join the lineup Tuesday night against the Pittsburgh Penguins.

Draisaitl has missed four games with an eye injury and concussion symptoms suffered Oct. 9 against the Winnipeg Jets. Caggiula, who also suffered a suspected concussion, has been sidelined five games.

The forwards’ return comes at the perfect time for the Oilers as they have struggled to put up the kind of offensive numbers expected from the young, fast club. Edmonton has scored just 14 goals this season, ranking them second last in that category behind the Montreal Canadiens despite a league-high shots per game of 38.9.

“We’re cleaning up the defensive part, but now we’ve got to get the offensive part going,” head coach Todd McLellan said after Saturday’s loss to the Philadelphia Flyers. “Perhaps a couple of players will be back in our lineup who will make us a little quicker and a little more skilled than we are right now. But if not, this group has to get it done.”

Draisaitl had a goal and two assists in his three games prior to being injured, while Caggiula was held without a point in the two games he played.
