Newcastle forward Anthony Gordon may be looking at some time off the field, having departed St James’ Park on crutches following the 4-4 draw with Luton.
At Saturday’s halftime, Callum Wilson took the 22-year-old’s place.
“I think he twisted his ankle,” said Newcastle boss Eddie Howe, who did not provide a time frame for how long Gordon could be out for.
“He is in a protective boot and the physios are doing the right thing.”
This season, Newcastle has struggled with injuries to important players.
Goalkeeper Nick Pope is now sidelined due to a dislocated shoulder, and midfielder Joelinton is expected to miss the remainder of the campaign due to a thigh injury.
Other players with injuries include Matt Targett, Elliot Anderson, Joe Willock, and Jamaal Lascelles.
Barnes makes goalscoring return
Harvey Barnes, a winger, returned on Saturday, which gave Newcastle hope.
After missing the previous four months due to a foot injury, he returned in the 63rd minute and netted Newcastle’s fourth goal to tie the game 4–4.
“I have been out for a long time and it has been a tough period for me,” Barnes said.
“I just wanted to come on and make an impact and I did but it wasn’t enough to win the game. But it is great being back out there.
“There will be a little bit of rust for a little bit but that goal will give me the world of confidence going forward and hopefully I can build on that and the team can build on that.
“There are still a lot of positives to take.”
