Luiz is close to a move to Paris for a fee which would be a world record for a defender.
Lampard, though, who is 36 in June, appeared on the Premier League's list of released players alongside striker Samuel Eto'o and left-back Ashley Cole as their contracts expire on June 30.
This does not mean his departure is inevitable, as Chelsea are still to clarify if the midfielder, who moved to Stamford Bridge in June 2001, will stay or move on.
Cole has suggested he is likely to leave Chelsea, while Eto'o will move on at the end of his one-season deal.
Meanwhile, Rui Faria, the Chelsea assistant manager, has had his stadium suspension reduced by the Football Association on appeal.
The FA announced Faria, who admitted two charges after he was sent off in the club's home defeat to Sunderland, will serve a four-match ban, with two games suspended.
