Giannis Konstantelias scores on Dortmund debut before suffering knee injury in 2-0 win
Borussia Dortmund defeated Hamburger SV 2-0 at Signal Iduna Park, but sporting director Ole Book confirmed fears of an anterior cruciate ligament injury for Giannis Konstantelias.
Opening Bundesliga win at Signal Iduna Park
Borussia Dortmund commenced their Bundesliga season with a 2-0 victory against Hamburger SV at Signal Iduna Park on Matchday 1. The hosts took an early lead in the 9th minute when forward Serhou Guirassy scored from an assist delivered by Konstantinos Karetsas. Dortmund controlled play throughout the first half and generated further attacking opportunities in transition. Deep into first-half stoppage time, Greek attacking midfielder Giannis Konstantelias produced a solo effort in the 45+1st minute, striking a shot that took a deflection before settling into the Hamburg net. The strike marked a scoring debut for the 23-year-old former PAOK player in the German top flight and established a two-goal cushion heading into halftime.
Second-half collision and forced substitution
The momentum of the match shifted six minutes after the restart when Konstantelias suffered a knee injury in the middle of the pitch. In the 51st minute, the midfielder attempted to win the ball back in the opposing half during a challenge with Hamburg player Bakery Jatta. His leg became entangled with his opponent, causing his knee to twist awkwardly before he fell to the grass in obvious pain. Dortmund medical staff quickly arrived on the pitch to administer initial medical attention and conducted specific mobility tests to assess ligament stability. Konstantelias remained on the ground for two minutes before being assisted off the pitch while limping heavily, leading to an enforced substitution in the 54th minute when Marcel Sabitzer came on in his place.
If someone leaves in tears, you can understand how they feel.

Medical concerns over cruciate ligament damage
Konstantelias was visibly emotional as he left the field, prompting immediate worry within the Dortmund coaching staff and medical department. Manager Niko Kovač consoled the Greek international on the sideline as he departed down the tunnel in tears. Club officials fear the player may have suffered a rupture of the anterior cruciate ligament, an outcome that could rule him out for the remainder of the season. German outlet Bild echoed these medical concerns following the match. Sporting director Ole Book addressed the situation directly in an interview with Sky Sports, confirming that the club is bracing for potential ligament damage while awaiting formal diagnostic scans.
That concern exists. We need to be a little cautious today, but we are definitely worried about a serious injury. Now the diagnostic tests will begin, we all hope for the best, of course, but we are also worried.
Diagnostic timeline and squad impact
Konstantelias will undergo a comprehensive magnetic resonance imaging scan to determine the precise extent of the structural damage to his knee joint. The diagnostic results will confirm whether surgical repair is required and establish an official recovery timeline for the attacking midfielder. While the 2-0 result secured three opening-day points for Dortmund, the potential long-term absence of their new signing poses an unexpected selection complication for Kovač. Dortmund will await the formal medical evaluation before issuing an official squad update ahead of their upcoming league fixtures.
