Aiden Bonar has underlined his elite athleticism on day three of the NAB AFL Draft Combine, with the talented prospect equaling the all-time standing vertical jump record.

The Dandenong Stingrays forward, who returned to the field in the middle of this season after two knee reconstructions, jumped 89cm in the test, drawing him level with Jordan Gallucci from last year's combine (Gallucci was drafted by Adelaide at pick No.15 last year). 

But Bonar's impressive efforts didn't stop there. He also recorded a 2.90-second 20-metre sprint, placing him equal second in the speed test.

The 18-year-old looms as one of the most interesting prospects to place ahead of next month's NAB AFL Draft on the back of his injury history, but he is strong, powerful and explosive, and has remained in clubs' thoughts during his time on the sidelines. 

Some recruiters see him pushing into the top-25 despite his limited exposure because of his knee issues.

Bonar was beaten to the top of the list in the 20-metre sprint by Northern Knights speedster Jack Petruccelle, who ran at 2.87 seconds to highlight is electric turn of pace.

Petruccelle entered the event as the clear favourite and ran 2.88, 2.87 and 2.87 in his three attempts. Kane Farrell impressed at 2.90 seconds, while Ben Miller and Nick Coffield, who both ran at 2.91, were also among the best performers.

Farrell, a neat-kicking left footer from the Bendigo Pioneers, and Miller, a tall forward from Western Australia, shared the honours in the agility test by running 8.10 seconds.

Another Bendigo pocket rocket Brent Daniels performed well with his sharp movement to run the agility test over 8.11 seconds.
