Anderson needs eye socket surgery

Anderson had initially received good news from an X-ray after being hit with an elbow during Saints' Europa League exit against Alashkert at McDiarmid Park on July 16.

But further tests have revealed the centre-back did suffer a fracture, which requires an operation to mend.

Saints boss Tommy Wright told the club's official website: "Ando has continued to experience symptoms and so we sent him for a follow-up scan and it has now revealed a fractured eye socket which wasn't initially detected.

"It's going to require an operation which will take place this Friday and will require a six-week recovery so we are looking at a seven week absence from now."
