Newcastle United goalkeeper Tim Krul will miss Sunday's clash with Southampton at St. James' Park with an ankle injury.

Krul was injured following a challenge from Jonathan Cristaldo during his club's 1-0 win over Metalist Kharkiv in the Europa League on Thursday.

Cristaldo's tackle left Krul in crutches following the match and the club confirmed on Friday that he was sent for a scan and will undergo further evaluation early next week.

"Newcastle United can confirm that Tim Krul was assessed by club medical staff on Friday and sent for a scan on Friday afternoon after sustaining an ankle injury in Thursday night's Europa League match against Metalist Kharkiv in the Ukraine," the club said in a statement. "Krul is now scheduled to see an ankle specialist on Monday for a further assessment."

With Krul unable to play, Steve Harper is likely to get the start between the sticks for the Tyneside club.

Newcastle sits in 16th place in the Premiership, just three points clear of the bottom three, but can give itself some much-needed breathing room with a win over the Saints, who are one spot ahead of the Magpies on goal difference.
