[4] In 2010 as a 16-year-old Docherty no longer played under-18 football for Phillip Island despite being picked for the Alberton Interleague team; he played 21 games for the Senior team and kicked 16 goals after his pre-season was hampered when he strained the quadratus lumberum muscle in his back, and as a result he missed selection in Gippsland Power's TAC Cup squad as an underage player.

[5] Docherty used his run and carry skills for the Power off half back averaging 22 disposals a game plus ranked second in the entire competition in mark from opposition kicks and rebound 50s in the TAC Cup.

[7] Despite his form for Gippsland, Docherty missed out on the initial Vic Country squad for the 2011 AFL Under 18 Championships; however, he was brought in for the fourth game of the carnival with an eye-catching display across half-back against WA in Geelong with 21 possessions and five rebound 50s.

[9] He struggled with his hip injury when he first arrived at Brisbane, almost immediately underwent surgery to correct a minor complaint he had carried through the 2011 season.

He then came back in round 5 and spent all of the 2012 playing for the Brisbane reserves side in the North East Australian Football League (NEAFL).

In the 2013 season he played 6 NEAFL games which he impressed in, he averaged 21 disposals per match and demonstrated that he can find the ball, racking up 30 plus twice.

At the end of the 2013 season as Michael Voss was sacked as Brisbane coach, Docherty was uncontracted with the Lions and told his manager he wanted to come home back to Victoria.

While he was away overseas he hurt his knee hiking, aggravating his injury from early 2013 and before leaving for Carlton's preseason camp in America he woke up one morning with a puffy eye, looking like he had been punched.

[15] He was still able to attend the camp but received a phone call to hear that his father Eddie had died suddenly after a heart attack at age 53.

It was a huge match against Collingwood on a Friday night at the MCG, in front of a crowd of 68,000, he started from the interchange bench and impressed with his poise under pressure as the Blues went down by 24 points.

Coach Mick Malthouse was sacked in late May and many players were criticised except Docherty, who had improved from previous seasons to average 21 disposals and 6 marks in his 19 games.

Averaging 25 disposals off half-back, he and Kade Simpson forged a strong partnership in defence, making it much harder for the opposition to score.

He injured his left anterior cruciate ligament during pre-season training on 15 November 2017, and missed the entire 2018 AFL season as a result.
