Ben Jacobs will be closely monitored by North's medical team this week, as he aims to prove his fitness ahead of the club's clash with Essendon.
 
The midfielder presented with concussion-like symptoms in the lead-up to Round 14, and was subsequently ruled out.
 
Meanwhile, Billy Hartung will miss the game against the Bombers with the Roos reluctant to put a time frame on his hamstring injury until further tests are conducted. Jarrad Waite is in a similar position with his calf complaint.
 
Key defender Ben McKay has escaped any serious damage to his knee after an incident in the VFL curtain raiser against Footscray and is a chance to play, as is Sam Durdin who copped a nasty poke in the eye.
 
North is hopeful Taylor Garner will be able to return to play this season, with his hamstring recovery listed at six to seven weeks.
