Manchester United defender Lisandro Martinez (25) will miss the remainder of the season due to a fractured metatarsal bone in his foot, the Premier League club said on Friday.
Martinez was carried off during United's 2-2 draw with Sevilla in the Europa League on Thursday after he fell to the ground clutching his right foot with no opponents nearby.
Fellow centre-back Raphael Varane (29), who was also injured and substituted at half-time during the quarter-final, first leg at Old Trafford, is expected to be out for a few weeks.
United said Argentine World Cup winner Martinez would make a full recovery in time for the start of next season.
"Everyone at Manchester United sends Lisandro and Rapha our best wishes for a speedy recovery," the club said in a statement.
