Arsenal fear Kieran Tierney’s knee injury will put him out for a number of weeks, with his Europa League quarter-final participation heavily in doubt.

The Evening Standard report that Arsenal are facing losing Kieran Tierney for both legs of the Europa League quarter-final against Slavia Prague through a knee injury. He’s still being assessed, but the initial fears are that he’ll miss a few weeks of action.

The Daily Mail add that Tierney will have a scan in the next 48 hours, at which point they’ll have a clearer indication of the length of his absence. But they also suggest the same fears of a few weeks out.

With the first leg of the quarter-final practically upon us now, there seems next to no hope of any Tierney involvement in the Emirates Stadium match.

Most likely, Cedric Soares will fill in, though Mikel Arteta might start to consider the possibility of using Bukayo Saka at left-back. He has Nicolas Pepe to play right-wing, and Saka has plenty of experience in the full-back position.

Regardless, it’s going to be a blow to Arsenal. Whether it means using a right-footed right-back on the left or the team’s top-performing winger in defence, Arteta is going to be making some sacrifices in the coming games.
