The Liverpool Echo reports that Sakho will sit out his side's clash against Newcastle United at Anfield on Monday night and is set to miss the FA Cup semi-final showdown with Aston Villa at Wembley on April 19.

The former Paris Saint-Germain defender will also miss the forthcoming Premier League games against West Brom, Hull and QPR, but the club are hopeful he will return in time to face Chelsea at Stamford Bridge on May 10. Toure is in line to deputise once more for Sakho against the Magpies and is set to form a central defensive partnership alongside Dejan Lovren. Martin Skrtel is still serving his three-match ban. Rodgers' side have slipped down to sixth the Premier League standings in recent weeks and will be targeting a crucial three points against John Carver's side who are winless in four games.
