Liverpool striker, Luis Saurez, is one of the main attractions, and he is joined by fellow Reds player, defender Sebastian Coates.
Suarez is one of the three over-age players allowed to be included, with Palermo’s Arevalo Rios and Napoli’s Edinson Cavani also selected by coach, Oscar Tabarez.
So, at least England will know what to expect when they play Uruguay, having also been drawn in group A along with Senegal and the UAE.
Uruguay have won the Olympic gold medal on two occasions, having first triumphed on their debut at the Games in Paris, in 1924, beating Switzerland 3-0.
They followed up, four years later, in Amsterdam, beating Argentina 2-1 in a replay after the first match ended all square, but they have not been anywhere near as successful since.
However, the South Americans, who join fellow CONMEBOL side, Brazil, in London, are expected to be one of the big challengers for the gold medal, having won the 2011 Copa America.
In addition, quite a few of the squad were part of the side that captured last year’s South American under-21 tournament.
The inclusion of Saurez, while good news for Uruguay, means that Liverpool will be without their star player for the start of pre-season training, but, when he does return to Merseyside, it could well be with a medal round his neck, maybe even gold, although his fellow Premier League peers will hope not.
