The Celtic boss missed the 1-1 draw against Hibernian and the goalless draw against Livingston at Parkhead as he was self-isolating following the club's controversial training trip to Dubai.
Lennon, assistant John Kennedy and 13 players had to self-isolate after Christopher Jullien tested positive for coronavirus and chief executive Peter Lawwell admitted the trip was "a mistake" and apologised to Hoops fans.
Ahead of the trip to Livingston on Wednesday, a defiant Lennon said: "Another player has been deemed positive, it is someone who is self-isolating.
"Everyone is negative bar two players.
"I think that is remarkable and blows out the water the way the trip has been portrayed in certain quarters of the media, by certain pundits and by certain government officials as well."
