The Oilers have four prospects competing at this year's IIHF World Junior Championship in Ostrava and Trinec, Czech Republic.
Eighth-overall pick from the 2019 NHL Draft, defenceman Philip Broberg, is suiting up for Sweden.
Also from the 2019 Draft, 38th-overall pick Raphael Lavoie is playing forward for Canada, joined by goaltender Olivier Rodrigue, who was selected 62nd overall in 2018.
The host Czechs feature forward Matej Blumel, whom the Oilers picked 100th overall at the 2019 Draft.
GERMANY 4 CZECH REPUBLIC 3
After scoring in Czech Republic's opening game against Russia, Oilers forward prospect Matej Blumel was held off the scoresheet on Saturday as the host nation dropped a 4-3 decision to Germany.
Both the Czechs and Germans are now 1-1 through two games in what's turning out to be a wide open, tightly-contested Group B that also includes Canada and the United States, with all five teams splitting their first two games.
Blumel played 12:35 in the defeat that saw Germany jump out to a 4-1 lead through 48 minutes before the Czechs made it close with two late goals but ultimately came up one tally short of tying it up.
The hosts will face USA on Monday at 11am MT and Canada on Tuesday at 11am MT to conclude the preliminary round schedule.
RUSSIA 6 CANADA 0
Raphael Lavoie and the Canadians also dropped to 1-1 at the tournament with a lopsided 6-0 defeat to Russia on Saturday.
After picking up an assist in Thursday's opener vs. USA, the Oilers forward and the rest of his squad were held off the scoresheet as the leading scorer for the QMJHL's Halifax Mooseheads played 14:05 and recorded three shots on goal.
For the second game in a row, Olivier Rodrigue was Canada's third netminder and did not dress. However, with both Nicolas Daws and Joel Hofer unable to stymie the Russians, the Oilers goalie prospect may get a chance to suit up as the preliminary round continues.
Canada will play Germany on Monday at 7am MT before taking on the host Czechs at 11am MT on New Year's Eve.
SWEDEN 5 SWITZERLAND 2
While the other three Oilers draft picks in action on Saturday suffered losses, Philip Broberg and Sweden stayed undefeated with a dominant 5-2 win over Switzerland.
The smooth-skating, stay-at-home defenceman played 20:06 in the victory and recorded one shot on goal, while LA Kings prospect Samuel Fagemo scored his second and third goals of the tournament to pace the Swedes.
Tre Kronor has now won a ridiciulous 50 consecutive preliminary round games at World Juniors, though they haven't captured gold since 2012.
Sweden will look to make it three consecutive wins to start this tournament when they face Kazakhstan on Monday at 7am MT before wrapping up round-robin play vs. Slovakia on Tuesday at 7am MT.
