The AFL handed stand-downs to the two timekeepers involved in the controversy at the end of Saturday night's Sydney-Collingwood match.

In further fallout from the match, Swans coach Paul Roos will contact the umpiring department for his own "please explain", particularly on an incident involving Collingwood captain Nathan Buckley and Sydney's Luke Ablett.

Also, the match review panel cleared Sydney key forward Barry Hall and Collingwood counterpart Chris Tarrant of incidents during the match.

Magpies coach Mick Malthouse was furious immediately after the match, which the Swans won by a point, saying the timekeepers had allowed the clock to run down at the end of the game despite the umpire signalling time-on.

Field umpire Stuart Wenn had made the signal when Swan Amon Buchanan marked in the back pocket and feigned a leg injury in an effort to run down the clock.

The final siren sounded soon after.

"It was determined 14 seconds of playing time was lost due to an error when the timekeepers failed to register a signal from umpire Stuart Wenn to stop the clock," the league said in a statement.

League operations manager Adrian Anderson added: "The timekeepers are two experienced AFL appointees who have been on our panel for five and six years respectively and have more than a decade of experience with senior football prior to joining the AFL panel.

"They are extremely disappointed that this error occurred."

The umpiring department will determine how long they are stood down, but they will stay on the time-keeping panel.
