The Chinese Football Association (CFA) has launched an investigation into Tianjin Teda's 4-1 Chinese Super League win over Tianjin Quanjian on Saturday, promising to "implement regulations strictly" if any impropriety is found.
The result hauled struggling Teda out of the relegation zone and into 14th place in the 16-team league, with the bottom two teams dropping into the second division at the end of the season.
"Following tip-offs and received reports, the Chinese Football Association has started an investigation into the CSL Round 26 game between Tianjin Teda and Tianjin Quanjian," the CFA said in a statement.
"A task force composed of the CFA's competition department, legal department, the commission of morality and fair play and the disciplinary committee will look into the case and gather evidence.
"The CFA will implement its regulations strictly if any anti-disciplinary activities are found."
The result denied Quanjian, coached by Italian World Cup-winning defender Fabio Cannavaro, the opportunity to move into third place and close in on a spot in next year's Asian Champions League.
Teda have struggled despite the acquisition of John Mikel Obi from Chelsea in January and remain deep in relegation trouble with 19 points from 26 games.
