AC Milan's Theo Hernández has suffered an ankle injury and will be out for at least one month, the club announced on Tuesday.
Hernández, who joined the Rossoneri from Manchester United in January, was forced off during the first half of their 2-1 Serie A win over Genoa last weekend.
He underwent surgery to repair a ligament tear in his right ankle, but the initial prognosis is that he will miss the rest of the season.
The news comes as a blow for Milan, who have struggled with injuries this season and are currently eighth in the league table.
Hernández has been a key player for Milan,Premier League Updates scoring six goals and providing three assists in just 14 appearances this term.
However, the club will now turn to other players to fill the void left by Hernández's absence.
AC Milan are likely to look to loan signings or new signings to replace him, while also potentially looking to recall injured players from their loan spells elsewhere in Europe.
Injury is a common problem for footballers, but it can also be a costly one for clubs like AC Milan, who will need to make some tough decisions about their squad going forward.
