The Newcastle manager, Alan Pardew, is considering an appeal against the red card that could see his captain Fabricio Coloccini suspended for three games.
Coloccini was dismissed in the 84th minute for a challenge on Luis Suarez that left the Uruguayan forward floored. Referee Anthony Taylor, on the guidance of his assistant, produced a straight red, which was met with disbelief by Coloccini. Pardew went on to the pitch as soon as the final whistle had been blown to seek clarification of the dismissal, and he was angered by comments from the Sky summariser and Wales manager, Chris Coleman, who labelled the tackle, "a coward's challenge".
"I've got no reaction to Chris Coleman's comments," he said. "We might have to accept it but I will discuss it with my secretary and everyone else at the football club to see what we think of that. I [have] seen the referee and I said to him I can see why he sent him off, I have no problem with that.
"Looking at it on the video it doesn't look too good from one angle in particular [but] from another he is putting his foot down to stop himself but he has gone into Suarez. Knowing Colo as I do, and I have spoken to him, I don't think there is any malicious intent there. It's a blow for us to lose our captain. He is my captain. I wouldn't have done it [walked on the pitch to see the referee] for any other player.
"Coloccini is a real top, top guy. I wanted to know for sure what it was before they discussed it or had any inclination of what it might have been. I wanted to know what it was for, he said it was serious foul play and I said OK. I don't want to make a big deal out of the referee because their morale must be very low."
Pardew's side had taken a 43rd-minute lead through a fine goal from Yohan Cabaye, the first time a Newcastle player had scored a goal at Anfield since 2004. The equaliser did not come from Suarez until the 67th minute, but it was a strike of breathtaking quality from the Liverpool forward, who took a long ball over his shoulder from Jose Enrique on his chest, held off Coloccini and slipped past Tim Krul in the Newcastle goal.
"It was a brilliant performance by Luis, a terrific performance," said the Liverpool manager, Brendan Rodgers. "It bodes well for us going forward. Newcastle are a good side but we were terrific today. I thought Luis was unplayable. I think Coloccini got sent off because he was frustrated. I don't think he could get near him today and he is a good defender. He couldn't get near him today. Coloccini has been a great player for Newcastle over these last couple of years, but Luis is so bright and so clever, he is a real world-class striker and on that form today he frustrates and provokes defenders."
Pardew agreed, saying: "He is a top player, there is no doubt about that. He caused us problems and when he plays the game in the right spirit, he is a fantastic player."
Liverpool maintained 12th position with the 1-1 draw. They have now drawn five of their last 10 games and Suarez has scored seven of their 13 Premier League goals.
Liverpool have also not won successive top-flight games for 14 months, but Rodgers added: "Our performance was outstanding. We were terrific. Our first-half possession and intensity was relentless. We just switched off before half-time. I said to the players, 'Listen, you've been brilliant, apart from conceding our goal'. I said we need to keep calm and control the game and, hopefully, the chances will come and there were many chances. Unfortunately, we didn't finish them off."
