Mohamed Elneny is wearing a protective boot following his injury against Sutton United in the FA Cup.

Elneny, who joined the Gunners last January, was substituted at half-time during the 2-0 win over non-league side Sutton.

After having a scan on his ankle, the 24-year-old was expected to be ruled out for at least three weeks.

But the injury may be more serious than originally thought, as the Egyptian has posted a picture on Instagram of his foot in a protective boot However, this may just be a precautionary measure from the club as they look to get Elneny back on the pitch as quickly as possible.

Meanwhile, Spanish midfielder Santi Cazorla has been ruled out for the rest of the season with another injury setback.

The 32-year-old has struggled with an ankle ligament injury since last October and was forced to have further surgery this week on a scar that had opened.

‘Everything was going well until I started to do some exercises on the bicycle,’ he said.

‘The skin opened again and the stitches gave in. We hope this is the last one and I can return as soon as possible.’
