Ex-Aussie international Harris's tweets land him with $3,000 fine

Ryan Harris had criticised Alex Ross's dismissal during Brisbane Heat's game against Hobart Hurricanes

Former Australia international Ryan Harris has found himself in hot water after tweeting criticism of an umpiring decision in the Big Bash.

Harris, who is currently employed by Cricket Australia as a high performance coach, took to social media to voice his opinion after Alex Ross was given out obstructing the field during Brisbane Heat's three-run defeat by Hobart Hurricanes on Wednesday.

Ross changed his running line and subsequently got between Jofra Archer's throw and the waiting gloves of Canes wicketkeeper Matthew Wade, though he later insisted he was trying to avoid injury by adjusting his path.

Despite the Heat's protestations, the batsman was sent on his way by the umpiring team of Geoff Davidson and Simon Fry at the Gabba, following consultation with TV official Simon Lightbody.

Harris felt the decision was wrong and wrote several messages - to both the Big Bash's official Twitter account and to Aussie international Glenn Maxwell - highlighting his views.

"It is very very embarrassing!! Absolutely shocking!!," he posted, before writing to Maxwell: "Common sense Maxi!! Horrible for the game!!

"More I see it the more ridiculous it is!"

The 34-year-old, who is currently coaching the Australian Under 19 side at the World Cup in New Zealand, was reprimanded by Cricket Australia on Friday.
