MARTIN KELLY has ruled himself out of action until at least the new year after injuring his knee.

Reds rocked by Kelly KO

The Liverpool full-back limped off late in yesterday’s 2-1 defeat at home to Manchester United after falling awkwardly and appearing to twist his right leg.

And scans have revealed that Kelly has suffered an ACL rupture of his right knee which will require ACL reconstruction.

He posted on Twitter: “What I can say is it’s not the worst injury I’ve had, and for sure I’ll be fighting for my place next year when I’m back fitter and stronger!”

The Reds also confirmed that Kelly’s back-four partner Daniel Agger, who was stretchered off the pitch 13 minutes before the England international, has suffered a significant bone bruise to his left knee.

The injury is not as bad as first thought after there were fears that the Dane may be out for the season with ligament damage.

But Agger will require further tests before a date is put on his recovery.

In a further blow for Liverpool boss Brendan Rodgers, Fabio Borini picked up swelling to his right ankle in yesterday’s Anfield clash.

The striker must wait for the swelling to reduce before a proper diagnosis can be given.
