ADELAIDE defender Graham Johncock says he knows he is on his last chance with the Crows after several misdemeanours during his roller coaster nine-year career.

Johncock was given a one-match ban for failing to attend a rehabilitation session earlier this season, which was his third strike, having previously being found guilty of lying to police and fleeing the site of a car crash and also being stood down by the leadership group for failing to meet the necessary standards of preparation during a difficult time in his life.

The 27-year-old didn’t think his actions in May this year warranted a one-week ban from AFL selection, but said he had lost respect from his teammates as a result of the incident.

“There’s only so much a club will take, so I’m definitely on my last chance,” Johncock said on Wednesday.

“I thought I made I inroads into [regaining] that [respect], but the incident this year definitely put a dent in that. I’ve had a few of those [misdemeanours] over my career and this year… I probably made a silly decision.

“Not everybody gets an opportunity at the elite level and I’ve been here at the club a while now. I’ve had a few chances and I just want to make sure when I walk away from the game that I don’t have any regrets.

“For me it’s just a day-to-day thing. The more I do certain things or put myself in certain situations the more I put myself at risk.”

Johncock was suspended, alongside teammates Bernie Vince and Matthew Jaensch, following Adelaide’s loss to North Melbourne in round eight.

Rookie Jaensch missed out on being drafted as an 18-year-old, after being kicked out of the South Australian U18s squad following an alcohol-fuelled incident at an official function.

He was warned about a repeat of any such behaviour when he was drafted by the Crows last year and admitted he thought he’d blown his second chance at an AFL career with his actions in Melbourne on May 15.

Johncock said he had provided support for Jaensch at the time.

“I had a few words with Jaenschy because he was pretty upset about it and it took him a while to get over,” Johncock said.

“I’ve been in that situations a few times, so I had a bit of a talk to him.”

Despite missing seven games through injury and suspension, Johncock has enjoyed a career-best season and is on track for a top-five finish in Adelaide’s best and fairest award.

The rebounding defender has earned praise for his on-field leadership, but says he’s unlikely to put his hand up for an official leadership role when skipper Simon Goodwin and veteran Brett Burton retire at the end of the season.

“I see everyone as being leaders in their own way,” he said.

“It’s taken me a while to adjust to the program and to speak up in meetings. My leadership comes out on the playing field and that’s where I let my actions do the talking.”

The Crows completed a light session on Max Basheer Reserve on Wednesday.

Promising youngster Patrick Dangerfield trained with his broken hand heavily strapped and could return to the side for the clash with the Brisbane Lions on Sunday.
