Newcastle schemer Miguel Almiron is facing a race against time to be fit for this summer's Copa America after being ruled out for the rest of the season with a hamstring injury.
The 25-year-old Paraguay international left the pitch in tears during the second half of Saturday evening's 3-1 Premier League victory over Southampton, suggesting the extent of the damage was significant, and the Magpies confirmed he will not figure in the final three games of the campaign on Wednesday morning.
A statement issued on the club's official website, www.nufc.co.uk, said: "Miguel Almiron will miss the rest of the season after suffering a hamstring injury in Saturday's 3-1 win over Southampton.
"The 25-year-old was withdrawn in the 64th minute against the Saints and, having been assessed by the club's medical staff, it has been confirmed that he will not be fit for the Magpies' final three matches of the campaign.
"The club have already been in communication with - and will continue to liaise with - the Paraguayan Football Association ahead of this summer's Copa America, which the player could still feature in depending on his recovery."
Newcastle have completed their move for Atlanta United playmaker Miguel Almiron, the club have announced.
The 24-year-old Paraguay international has joined the Magpies on a five and a half-year deal for an undisclosed fee believed to be in the region of £20million, eclipsing the £16million they paid for England striker Michael Owen in 2005.
Almiron told NUFC TV: "I'm very happy and eager to start and to meet my new team-mates. The league is very competitive, this is a historic club, and Rafa Benitez himself were the main reasons why I am here now.
"I think it is a great responsibility, something beautiful for me, and I will try to offer the best I can to repay the trust the club put in me."
