Frank Lampard has issued a positive update on Christian Pulisic, saying the winger's hamstring injury is very minor and he is already back in training.
However, the American will not be fit enough to play against Rennes in the Champions League on Wednesday night.
Pulisic withdrew from the warm-up before Chelsea's Premier League win over Burnley last weekend, leading to fears he could be set for a lengthy spell on the sidelines.
But Lampard has revealed a scan on the former Dortmund star's hamstring has revealed the damage isn't as bad as first feared.
