SOUTHEND United defender Joe Gubbins missed Saturday’s FA Cup clash with Charlton Athletic due to an Achilles injury.

The left-sided centre-back had started three of the last four matches prior to the Shrimpers’ game against the Addicks at Roots Hall.

But Blues boss Kevin Maher remains unsure how long the former QPR defender will be missing for.

“We’re not sure yet,” said Maher.

“We’ve got the scan back but we’re waiting to see what the treatment will be and how long it will be too.”

The Shrimpers host Yeovil Town at Roots Hall on Saturday.
