Chelsea will be without captain John Terry for Saturday's Premier League match at home to relegation-threatened Wigan Athletic with the centre back suffering from an inflamed knee, manager Rafael Benitez said.
.
'' It's a setback, but not serious '', Benitez told reporters on Friday.
.
The former England captain has been dogged by a knee problem this season, returning to action in January after two months out.
.
Benitez said their Czech Republic goalkeeper Petr Cech and Senegal stricker Demba Ba were both available after pulling out of midweek internationals through injury.
.
Ba suffered a broken nose in the 3-2 league defeat at his former club Newcastle United last weekend and has been training in a protective mask.
