Graham Potter has confirmed N'Golo Kante could be out until the start of March with his hamstring injury.
Kante has been sidelined since August after suffering a serious injury against Tottenham. Since then, the France international has undergone surgery on the problem but is not close to returning.
Chelsea take on Bournemouth on Tuesday evening and Potter has confirmed his side will be without six players for the game at Stamford Bridge. Kante, Ruben Loftus-Cheek, Wesley Fofana, Ben Chilwell, Mateo Kovacic and Hakim Ziyech will all be out for the game.
