The AFL has asked Collingwood and its star Jordan De Goey to explain an incident that occurred late in the Pies' Gather Round win over Hawthorn on Sunday evening.

Within the final five minutes of the narrow victory, broadcast footage showed Magpies ruckman Darcy Cameron at the bottom of a pack with blood trickling from his nose.

Before the resumption of play, De Goey's tattooed hand was captured reaching down to clear said claret, likely in an effort to held Cameron avoid blood rule detection and thus remain on the ground.

The adjudicating umpire, however, did sight Cameron's injury before asking the former Swan to make his way from the ground.

According to reports from 7 News' Mitch Cleary, the league has asked both the Pies and their hybrid threat for an explanation on the incident.

However, as there are no rules regarding the clearing of blood from a teammate's face or person, no sanction appears likely to arise.

De Goey and his Magpies will earn the opportunity to add a third win on the bounce when they return from their bye to face Port Adelaide at the MCG on Saturday, March 20.
