N'Golo Kante will miss Chelsea's home clash with Newcastle on Saturday although Mateo Kovacic could be fit.
The Chelsea boss revealed his frustration at the fact the former Leicester man was ruled out by France over the international break, but did not report back for assessment until after his country's second game last week against Iceland.
Lampard also told his press conference that defender Antonio Rudiger is back in training but unlikely to feature, while centre-back Andreas Christensen remains out.
The Blues are in improved form after a stuttering start to the season and will be looking for their fifth straight win in all competitions against Steve Bruce's side, who secured a much-needed 1-0 win over Manchester United before the international break.
Newcastle, who are 16th and just a point clear of the bottom three despite that win, have Matt Ritchie and Florian Lejeune out injured although Bruce confirmed the duo are both making good strides in training and should be back by the end of the month.
Matty Longstaff, who scored the winner on his full debut against the Red Devils, is expected to keep his place in midfield, with Bruce admitting he cannot leave the youngster out after his recent heroics.
