PROMISING North Melbourne draftee Mitch Hibberd has been sent for scans after suffering a serious right knee injury in the VFL on the same knee he had reconstructed in 2013. 

The 19-year-old went to turn and chase a loose ball near the wing when his foot planted in the turf, forcing the yet-to-debut Kangaroo to fall to ground clutching the knee.

Hibberd looked in obvious pain as trainers took him off the ground on a stretcher, after the innocuous incident happened in the second quarter of VFL affiliate Werribee's seven-point loss to Port Melbourne.

Young Roo to debut

A North Melbourne spokesman told AFL.com.au Hibberd had been sent for scans, with the club likely to provide a further update on Monday.

Hibberd, who was recruited with pick No.33 in last year's NAB AFL Draft, has had a luckless run with injury over his junior career.

The 190cm half-back underwent a right knee reconstruction at the end of 2013 followed by a right shoulder reconstruction, which ruled him out of the 2014 draft.

More recently, Hibberd was sidelined for a month after suffering a displaced kneecap in the VFL in May.

Despite the setbacks, Hibberd worked hard in his rehabilitation and impressed North's recruiters at last year's under-18 championships and draft combine.

The Kangaroos were so encouraged by Hibberd's development they rewarded him with a one-year contract extension in May, tying him to the club until at least the end of 2018.

Meanwhile, North ruckman Majak Daw also faces a nervous wait to see if he has suffered ligament damage in his ankle after going down in the same VFL match.

Daw landed awkwardly on his left ankle after leaping and stomping on teammate Braydon Preuss's foot in a ruck contest late in the first quarter.

The 25-year-old went straight into the change rooms and did not take any further part, watching the rest of the game from the interchange area.

Daw, who has featured for the Kangaroos on three occasions so far this season, is out of contract at season's end.
