Dumbrell says doctors’ advice over the coming week, or an arrival in the meantime, will shape his Newcastle participation
“We’re waiting patiently, or getting more nervous as the days go on, getting closer and closer,” Dumbrell told Supercars.com.
“[Going to Newcastle] really depends on what doctors say over the next week or so.
“Obviously these things aren’t an exact science, it’s hard to guess or estimate when it’s going to happen.
“We’ll have to make that call on Wednesday next week or whether or not I head up, or continue to wait in Melbourne.
“Hopefully it happens this week, or that good planning’s gone to waste!”
While Dumbrell has not been able to visit Newcastle pre-event, he hopes to be able to gain some insight on the new street circuit from Jamie Whincup, who Dumbrell has joined for the Supercars enduros since 2012.
