Liverpool forward Mohamed Salah will be available against Arsenal and Manchester City as he will not face a ban for diving.
He tumbled after pressure from defender Paul Dummett, who appeared to put his hand on the Egypt international.
And the Football Association has decided not to pursue a charge as there was contact, so the incident did not meet the threshold for a diving charge.
Had the FA opted to investigate, Salah could have missed the games against Arsenal on Saturday and City next Thursday.
Premier League leaders Liverpool were 1-0 ahead at the time of the spot-kick and Newcastle boss Rafa Benitez felt Salah went down too easily.
“At the start of the second half there was a soft penalty,” he said after the game.
“It’s hard when you’re 2-0 down. If you have chances and don’t take them or make mistakes it is difficult.
“The first goal is a mistake and the second is key in terms of confidence.”
