Eriksen suffered an ankle injury as a result of a challenge from Reading forward Andy Carroll, who was later sent off for two yellow cards.
Christian Eriksen of Manchester United will be out until at least late April after suffering an ankle injury in his team’s FA Cup win over Reading on Saturday.
Erik ten Hag, manager of Manchester United, believes the club has “players who can fill the gap” left by Eriksen’s absence.
“On deadline day it’s difficult [to bring in a replacement]. “You can’t make policy based on such severe injuries,” he said.
“However, we have players in the midfield who are good.”
This season, the Danish midfielder has made 31 appearances for United.
In the summer, the former Ajax, Tottenham, Inter Milan, and Brentford player signed a three-year contract at Old Trafford.
“He is expected to be out for an extended period of time,” the club said in a statement.
“There is hope that Christian can return in time to play a role in the final stages of the season.
“While investigations are ongoing, preliminary estimates indicate that Eriksen will be out until late April or early May.”
