Liverpool defender Glen Johnson has revealed he sustained a hamstring injury in Saturday's 1-0 defeat against Stoke.

The full-back made his first appearance of the season as a late substitute at the Britannia Stadium.

Johnson missed the start of the season with a thigh problem and he could now be out again with the hamstring injury.

Johnson revealed on Twitter: "Can't believe my luck at the mo. Done my hammy again today! Hopefully be back soon!"

The news will be a blow for Reds boss Kenny Dalglish as fellow right-back Martin Kelly is also recovering from a hamstring injury of his own.
