Shortly after receiving his first yellow card, Russia's Smolnikov received another one for chopping down Laxalt and subsequently left his team and the field.
Sitting at the podium in the post-match news conference following Uruguay's 3-0 victory over Russian Federation, a reporter asked him why he often wore a sad expression.
A resultant corner from one such strike brought the third goal as Cavani was close at hand to nod in after the goalkeeper had done well to keep out a glancing header from Godin.
The coach rejected the notion that Smolov's presence alongside him guaranteed the striker would be starting, and suggested his yellow card when he did come on against Egypt could influence selection decisions, to avoid any potential suspensions for the second round. Tomorrow's match will decide on the victor of their Group A, which also enrolls the teams from Saudi Arabia and Egypt.
While Uruguay are brimming with confidence after keeping a clean sheet in a three-match World Cup group stage for only the second time, Russian Federation must somehow bounce back fast if they are not to exit the tournament much quicker than a nation dreams of.
Luis Suarez grabbed his second goal of the tournament to open Uruguay's account with a free-kick after 10 minutes when he struck a low free-kick into the bottom corner that should have been easy pickings for Russian Federation keeper Igor Akinfeev.
The party continued inside the stadium as the fans flocked in and made an almighty racket, before Russia's positivity was punctured within 10 minutes by Luis Suarez.
He has become a key figure for Uruguay at this World Cup. More recently, the team finished fourth in South Africa in 2010 and made the round of 16 in Brazil four years ago.
England v Belgium. What will the score be?
Marcus Rashford could also come in for Raheem Sterling , who has underperformed so far in Russian Federation . The players' performance will also be a factor in who wins the golden ball (the tournament's best player).
Edinson Cavani celebrates Uruguay's third goal.
In the other match of this group of Saudi Arabia for the first time since 1994 won the world Cup.
On a personal level I'm happy to move forwards, with the team we continue to make history.
Salem Aldawsari scored with nearly the last kick, shooting from a tight angle inside the Egypt penalty area and poking the ball past El Hadary. The decision was confirmed after a video review.
Earlier, a mix-up by Andres Iniesta and Sergio Ramos gifted Morocco its first goal of the World Cup.
At the opposite end of the pitch, Suarez provided that extra touch of quality that Saudi Arabia - or a half-fit Mohamed Salah - could not.
Seeing as the Russians' next match will be against Group B winners Spain in the round of 16 on Sunday, it's hard to disagree with their manager's assessment.
Uruguay are the first side to win all three of their group games without conceding a single goal since Argentina in 1998 (seven goals scored, none conceded).
