Mexican soccer star Raul Jimenez underwent surgery Sunday night after fracturing his skull during a Premier League game in London, his team confirmed.
The 29-year-old forward was playing for his club Wolverhampton against Arsenal -- when he collided with Brazilian star David Luiz while going after a corner kick in the 5th minute of the game.
The two banged heads -- and it was so loud, you could hear the impact on the TV broadcast.
Medical personnel rushed on to the field to treat both men -- but it was obvious Jimenez was badly hurt ... and they called for the stretcher.
He was eventually transported to a nearby hospital -- where he was diagnosed with a fractured skull and underwent surgery.
Wolverhampton issued a statement Monday morning -- saying, "Raul is comfortable following an operation last night, which he underwent in a London hospital."
"He has our love and support as he begins a period of recovery. We're all with you, @Raul_Jimenez9."
As for Luiz, he was bandaged up and stayed in the game.
Wolverhampton ended up winning the match 2-1.
