FORWARD Aaron Black has withdrawn from North Melbourne's practice match against Geelong on Friday night with a virus and has been replaced by Mason Wood.
 
North Melbourne announced Black's withdrawal via its club Twitter account on Friday morning.
 
After an injury-plagued first season with North in 2013, Wood has played in the Roos' opening NAB Challenge game against Carlton.
 
The 20-year-old is a 192cm lead-up forward who has impressed with his work ethnic and endurance this pre-season.
 
The former Geelong Falcon should push to make his debut this season.
