Buckley on Twitter over Witts blow-up

Collingwood coach Nathan Buckley has taken to Twitter to concede that he overstepped the mark during a fiery boundary line exchange with ruckman Jarrod Witts.

A furious Buckley grabbed Witts by the jumper and gesticulated fiercely during the third quarter of his side's 29-point loss to Hawthorn at the MCG on Saturday afternoon.

But with the moment's heat having subsided, a contrite Buckley could see that he had erred.

"Incident with Wittsy says more about his coach than the player. Still room for challenges to be laid in this game but too overt today," he tweeted on Saturday night.

The tweet gained enormous traction, obtaining more than 60 re-tweets within half-an-hour.

Buckley's antics did not appear to have a detrimental impact on Witts, with the forward improving in the game's latter stages to finish with two goals.
