Wardlaw will miss North Melbourne's clash with the Western Bulldogs on Saturday and next week's encounter against the Suns after copping a knock late in Thursday's session.
The 20-year-old midfielder was initially assessed for a shoulder injury, but he later reported symptoms consistent with a head knock and has been placed in the AFL's concussion protocols.

The Magpies have loaded up on star power, with Jordan De Goey (groin), Brody Mihocek (hamstring), Scott Pendlebury (bicep), Joe Richards (foot) and Oleg Markov (back) all returning.
"This was the game that we set him for and he's ticked all his boxes," Collingwood coach Craig McRae said of De Goey, who last played in the four-point win over Adelaide on May 18.
Walker returns for the Crows in a vital boost ahead of Saturday's home match against GWS.

The Giants have been bolstered by the return of Stephen Coniglio from a dislocated shoulder, while defenders Harry Perryman and Isaac Cumming are also back.
