Andrew Swallow has made his way back into North Melbourne's squad of 25 to face Sydney.
He and Braydon Preuss come back to North's squad on the back of injuries to Taylor Garner and Aaron Mullett.
Mullett has been ruled out due to a preexisting hand injury, breaking his hand two weeks ago against Gold Coast.
Garner will miss the clash with soreness.
Both players were returning to the side after missing last week's win over Adelaide.
The two have been in career-best form for the Roos.
The full teams will be finalised at 5pm on Friday.
