In case you missed it, that was Pavel Datsyuk that contributed to Mourinho's tumble by extending his hand out to one of sport's ultimate villains.
But little did he know that an embarrassing moment was bound to happen.
The Portuguese football legend caused a stir in the Russian press with many outlets trying to guess why a regular KHL game between Avangard and SKA attracted Mourinho's attention.
It is not the first time Mourinho has hit the ground at a public event - he tripped over outside England's match against Spain at Wembley last September when attempting to step across a rope barrier.

The 45-year-old Norwegian football manager replaces former manager Jose Mourinho who was thrown out of the club because of poor results.
With the weekend to himself, Jose Mourinho took up the offer of being guest of honour at the KHL ice hockey match between Avangard Omsk and SKA St Petersburg in Balashikha, Russia on Sunday.
He inspected the room full of skates for the players before watching the side get put through their paces on the ice before the evening's games. Videos of the 56-year-old Portuguese manager falling on a red carpet on the ice rink in Balashikha went viral on social media after the accident.
United have not lost since Mourinho's dismissal, with caretaker manager Ole Gunnar Solskjaer overseeing nine wins and draw once over that 10-game span. He went on an eight games winning run before drawing at Burnley.
