Manchester United centre-back Lisandro Martinez has been stretched off the field in the latter stages of his side's Premier League contest with Crystal Palace at Old Trafford.
Martinez was involved in a race with Palace forward Ismaila Sarr down the left before falling awkwardly and appearing to jar his knee, and he then had to be stretchered off the field.
The Argentina international looked in serious discomfort, and the initial suggestions are that the defender could have suffered a severe knee problem, which might end his season.
Martinez was out between September 2023 and January 2024 with a serious foot injury, and he then missed almost two months later in the same season due to a knee problem.
The 27-year-old will now be assessed before a statement is made, and Red Devils head coach Ruben Amorim will also be asked about the situation in his post-match press conference after the contest with Palace.
Matthijs de Ligt was ultimately introduced as Martinez's replacement following a period of treatment on the field.
