Liverpool defender Martin Kelly ruled out until new year while Daniel Agger could miss rest of the season The full-back limped off late in the 2-1 defeat at home to Manchester United after falling awkwardly and appearing to twist his right leg. Liverpool have yet to confirm the extent of the problem but Kelly himself does not expect to be back for at least three months. "What I can say is its 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!" he wrote on Twitter. Manager Brendan Rodgers' injury concerns do not end there with fears that centre-back Daniel Agger could be ruled out for the rest of the season as he awaits the results of a scan on his left knee. Forward Fabio Borini is also set for a spell on the sidelines with a bruised foot and swollen ankle. Speaking after the game, Liverpool manager Brendan Rodgers said: "Fabio (Borini) had a badly swollen ankle. Agger's doesn't look good, the medics were saying it might be a medial ligament.
