Didier Drogba has "trained well" and looks set to return for Chelsea's Premier League clash with Wolves on Saturday.
The Ivory Coast striker missed last weekend's goalless draw with Aston Villa and the midweek Champions League victory over Spartak Moscow with a virus.
However, the six-goal joint leading scorer returned to training on Thursday and is in line to return to the first-team squad when Wolves visit Stamford Bridge.
"The players who played in Moscow were given the day off," said assistant first-team coach Paul Clement.
"The substitutes and players recovering from injury or illness, like Didier Drogba, came in the afternoon and we had a good session with them.
"Didier looks good and he trained well."
Meanwhile, the game will come too soon for Frank Lampard as the England midfielder continues his cautious recovery from hernia surgery in August.
"Frank is progressing really well," explained Clement."He had a terrific session earlier in the week with (assistant fitness coach) Chris Jones doing some individual work, he's really pushing himself.
"Frank is very frustrated and can't wait to get back. We have missed him and we look forward to him returning."
