UPDATE: Former South Fremantle forward Cory Dell'Olio is set for a dream AFL debut at a packed MCG on Saturday after the Bombers this morning upgraded him to their primary list and picked him in the team.
The 22-year-old small forward, taken by the Bombers at pick 29 in last year's rookie draft, has emerged as the Bombers juggle a spate of soft-tissue injuries.
Dell'Olio was upgraded in place of Brent Prismall, who has been on the long-term injury list since rupturing his ACL in round 19 last year.
"Cory had a terrific pre-season and we were impressed with his form early in the NAB Cup campaign and as a result of that form, we are giving him the opportunity he deserves," Essendon's general manager of football operations Paul Hamilton said.
Courtenay Dempsey became the latest of a string of Bombers players to suffer hamstring issues in last weekend's clash against Gold Coast.
Dempsey was selected but Jason Winderlich, David Myers and Nathan Lovett-Murray are all out of contention with similar problems, while ruckman David Hille and midfielder Mark McVeigh are nursing calf muscle strains.
The Bombers will have only a four-day break between Saturday's clash and the traditional blockbuster against the Magpies.
Dell'Olio, one of the most prolific small forwards in the WAFL in recent seasons, has been in solid form for Essendon's VFL affiliate Bendigo Gold.
Though goalless in last weekend's clash against Casey, he had kicked five goals in two games prior to that to press claims for a senior berth.
Dell'Olio kicked 109 goals in 58 matches for South Fremantle, including 55 goals in 2011.
