VIDEO: Moment Jonathan de Guzman was knocked unconscious
This is the moment Jonathan de Guzman suffered the injury which ruled him out of Swansea City’s game with Manchester United.
The Swansea midfielder was on international duty with the Netherlands when he was knocked unconscious in a clash of heads with teammate Dirk Kuyt.
The pair missed Wednesday's friendly against Portugal.
de Guzman will be sidelined for seven to ten days, making him unavailable for Saturday’s season opener against the Premier League champions.
The 25-year-old could also miss next week’s Europa League Play-Off first leg against Romanian side Petrolul Ploiesti at The Liberty.
Fenerbahce star Kuyt needed stitches following the nasty accident, and is a doubt for Wednesday's play-off round of the Champions League against Arsenal.
