Leeds United have confirmed that Stuart Dallas will undergo surgery after sustaining a femoral fracture in the 4-0 defeat against Manchester City on Saturday.
Following a challenge on Jack Grealish in first-half stoppage time, the 31-year-old required medical attention before leaving the pitch on a stretcher.
The versatile midfielder, who has played in every Premier League game for the Whites since their promotion from the Championship in 2019-20, is now set for a lengthy spell on the sidelines.
A club statement on their official website read: "Stuart was kept overnight at Leeds General Infirmary and will now travel to London for surgery and further tests.
"It is impossible to put into words just how important Stuart is to Leeds United on and off the field.
"Anyone who knows Stuart, knows he will come back from this stronger than ever, and in the meantime, he is sure to make his presence known at both Thorp Arch and Elland Road."
Dallas, who was voted as Leeds' Player of the Year last season, has contributed to 46 goals in 267 appearances across all competitions since joining from Brentford in 2015.
Leeds captain Liam Cooper is also set to be assessed after feeling discomfort in his knee during the warm up on Saturday, though head coach Jesse Marsch is hopeful that the defender has not sustained a serious injury.
The West Yorkshire outfit currently sit 17th in the Premier League table, just two points above the relegation zone with 18th-placed Everton having a game in hand.
