Arsenal boss Mikel Arteta has admitted that he is not sure when Scotland international Kieran Tierney will return to action for the Gunners.
Tierney missed last night’s goalless draw with Crystal Palace thanks to a muscle injury. He was a real miss for Arsenal, as they missed the attacking threat he brings down the wing.
Faces a scan to determine injury
Now Arteta has confirmed that he might well miss the upcoming game against Newcastle thanks to the muscle injury. He will know more after Tierney has an MRI scan later on Friday.

“Kieran’s progression in the last few months has been incredible, and now it is time for another player to step in. He’s going to have an MRI scan tomorrow and see how he is” he said.
“We don’t know (how long he will be out for), we will probably know more tomorrow (Friday) after testing him and how long he is going to be out for. It was a big disappointment to lose him and hopefully he will be back with us shortly” Arteta concluded.
Arguably best player this season
It would be a real blow for Arsenal if Tierney is out of action for a significant amount of time. He has arguably been Arsenal’s best player this season. They will struggle to replace him in the side should he be out for a while.

Scotland boss Steve Clarke will also be taking a keen interest in the results of Tierney’s scan.
He is one of Scotland’s most important players. A major injury would be a concern with Scotland having some big games in the months to come.
