Kieran Tierney has suffered another injury setback on loan with Real Sociedad, with his manager confirming a hamstring rupture.

Arsenal loanee Kieran Tierney appears to have suffered his second hamstring injury of the season with Real Sociedad, after being forced off in the first half of their match against Celta de Vigo on Tuesday night.

Tierney has been on loan in Spain since August, but a hamstring injury in September forced him out of action until December.

After two months on the sidelines, the Arsenal man broke back into the Sociedad side, starting every league game for the next month and a half.

But it looks like a new injury will bring that run to an end.

Just 39 minutes into Real Sociedad’s game away to Celta de Vigo on Tuesday, Tierney pulled up with an injury and was substituted.

After the game, head coach Imanol Alguacil broke the news that it appears to be a hamstring rupture.

“We are going to wait for the relevant tests to be done, but it is clear that it is a hamstring rupture,” Alguacil said.

“A shame, because with Aihen [Munoz] out, even if (potential new signing) Javi Galán comes, it is important to double up in positions with the games we are going to have to play.”

If the bad news is confirmed, you’d expect a month out of action. With Tierney already having suffered a two-month hamstring injury earlier this season, one month might even be too optimistic.

It’s another setback for Tierney and Real Sociedad, who are currently fighting for European qualification, as well as making the Copa del Rey semi-finals and the Champions League last-16.

Tierney now looks set to miss the upcoming tie against Paris Saint-Germain with his loan club.
