Uh oh! Adelaide Crows ruckman Reilly O’Brien has accidentally tweeted his game notes for this weekend’s matchup against Nic Naitanui.

In a now-deleted tweet, O’Brien publicly detailed his strategy on how to combat the Eagles star to his 2000-plus followers.

Crows ruckman Reilly O’Brien accidentally tweeted his game notes of how to combat Eagles star Nic Naitanui in this weekend’s matchup.

“Run off him hard, he is lazy and unfit,” O’Brien’s tweet said.

“Will have a field day getting ball and marking everything.

“Get to front and have grunt around the ground, and get ball on deck, beat him in this area.”

The Crows told Fox Footy that O’Brien’s phone “had gone erratic in recent times”, with private notes somehow getting published to his social media.

The 24-year old responded by owning up to his blunder in a video posted to Twitter, holding up his broken phone.

“Check this out – my phone has decided to cark it, and I’ve had an absolute ‘mare on my social media today,” he said in the video.

“I tweeted some of my game notes in my Notes on my iPhone, I take these notes every week before the game to try and pump myself up and get a bit of confidence going into the game. Make a few things up, as you can see in the notes.

“Coming up this week who I think probably is the best ruckman in the competition, Nic Nat, I was just trying to get some confidence and get going.

“I’ve really put the pressure on myself now, so I’ve really got to walk the walk and try and get a kick against the superstar that is Nic Nat. So we’ll see how we go.”
