Hwang Hee-chan scored the equaliser as Wolverhampton Wanderers drew 2-2 with Newcastle United on Saturday but the hosts suffered a major blow when forward Pedro Neto was carried off a rain-swept Molineux pitch with a hamstring injury.
Newcastle, who stretched their unbeaten streak to six games, are sixth in the Premier League with 17 points after 10 matches. Gary O'Neil's Wolves, unbeaten in the last five games, sit 12th on 12 points.
"A good performance, and hopefully Pedro won't be out too long," O'Neil told Sky Sports.
"For the boys to be able to put in a performance like that against a Champions League team that I saw pull apart PSG not too long ago is a big effort for them, so good point," he added. "But you feel like if a few things had maybe just gone our way, we were value for three (points).
Neto's injury put a damper on what was an otherwise entertaining, end-to-end affair, the potential consequences of the Portuguese winger's loss obvious on the concerned faces of Wolves fans.
"It's a big cost, I'm not going to lie," Mario Lemina, who netted Wolves' first goal in the 36th minute, told BBC. "I hope it's not going to be a big injury, we're all with him right now."
O'Neil said the severity of the injury would be known in the next few days.
"Any team in this league would miss a player of Pedro's quality," he said.
Hwang levelled in the 71st minute with a goal Newcastle could have avoided had keeper Nick Pope caught a free-kick rather than punched it out. It was redemption for the Korean forward after his rash first-half tackle led to a penalty for the visitors.
"I feel a little strange," Hwang said. "After I gave them a penalty I felt so sad, so I really wanted to do something for my team.
"After the first half, everybody said to me 'you can do it, keep going'. They gave me trust. I scored again and I am so happy to help the team."
Callum Wilson netted twice for Newcastle before the interval, first in the 22nd minute when keeper Jose Sa crashed into a teammate and let the ball slip from his grasp. Wilson pounced and fired home with an overhead kick.
"It was certainly a tough game for us," Newcastle manager Eddie Howe said. "I thought two really good teams and probably a really good spectacle for the viewers."
