(NewsNibs) - During the opening game of the ice hockey tournament, key defenseman Jiříček sustained a knee injury that has since sidelined him for the duration of the event. The incident occurred when Jiříček became entangled with opposing player Juraj Pekarčík, resulting in a fall that led to his injury. Despite initially leaving the ice with help and making an attempt to return, Jiříček was compelled to leave once more after a second fall, after which he did not return to the game. This injury echoes a familial pattern of sorts, as Jiříček's elder brother David also encountered a knee injury at a junior championship two years ago.
