Roger Johnson and Wayne Hennessey clashed during Wolves' defeat to Bolton Wanderers yesterday.
The Mail on Sunday says Johnson almost came to blows with his own goalkeeper Hennessey.
Wolves were drawing 0-0 when the pair flared up over a failed clearance. They went on to lose 3-2 to Bolton.
Wolves boss Terry Connor said: "That incident was two players showing both passion and determination to get the right result." He admitted he had to berate both men at half-time, when they shook hands in the dressing room.
