Poland lost their opener to Senegal and rang the changes, bringing Saints ace Bednarek for last night's match.
They fared no better as they were torn apart by an exciting Colombia side, who won 3-0.
Bednarek kept the score down a little, making one goalline clearance, but was also booked for his efforts.
He failed to make a tackle and it is questionable whether he will be selected for Poland's final game against Japan.
Bednarek made five Premier League appearances for Southampton last season, breaking into the team over the final few weeks of the campaign.
With his World Cup coming to an abrupt end at the group phase, Bednarek will now return to Southampton's pre-season training around mid-July.
Here is a look at how Southampton fans reacted on Twitter to his performance...
I feel for Jan Bednarek. Incredibly inexperienced at international level, has hardly played for most of the season and has now been thrown in as the central centreback against Falcao and James in a must win World Cup game. #saintsfc— Lucy Highnett (@lucyhighnett) June 24, 2018
Bednarek has really been let down by his team today. Feel sorry for him #SaintsFC— Saint Harris (@LHarrisSFC) June 24, 2018
