A former striker of Brentford has been admitted to the hospital with a potentially life -threatening injury.
De Ster played in the Bundesliga match between VfL Bochum and Heidenheim on Friday evening in a collision that saw the lower-placed side of the third of the bottom of the German top flight.
The game ended 0-0 and did not put any of both parties in their bids to stay in the Bundesliga for another campaign, because the season is coming to an end.
But the focus after the game was elsewhere, with attacker Philipp Hofmann rushed to the hospital on the back of an annoying collision with Marvin Pieringer for a few minutes in the game.
While Pieringer was withdrawn, Hofmann was replaced after a treatment on the field, with a club statement that revealed that his issue was 'potentially life -threatening'.
Bochum revealed that their husbands had suffered a rib fracture, where the rib drilled in his rib skin and caused a lung deposit.
They said he had undergone a small operation, in which the 32-year-old underwent a thoracic drainage to restore lung function.
He stays in the hospital for further treatment and observation until he was healthy enough to leave.
Club director Dirk Dufner visited him in the hospital on Saturday to give him his best wishes, although it now seems likely that he will miss the rest of the season.
Hofmann played 33 times for Brentford in the championship between 2015 and 2017 and scored four goals. He also played for Shalke and Eintracht Braunschweig in his career.
In the meantime, goalkeeper Kevin Muller was also taken to the hospital after a collision of heads with Ibrahima Sissoko during the game, with the stop unconscious when he tried to hit a ball in the box.
He was placed in the repair position by teammate Tim Sierleben, set up with privacy screens while he was treated by medical staff for a total of 11 minutes on the field.
