Bontempelli suffered the setback in Wednesday's loss to Melbourne, however was able to play out the match after initially requiring treatment off the field on multiple occasions.
Bulldogs’ Head of Sports Medicine Chris Bell has since revealed Bontempelli will be a test for next week's match, with further assessment required before a final call is made on his selection.
“Like any ankle sprain, he has some pain and swelling that we are managing in the early part of this week,” Bell said, with the club's website.
“We will work through a process with Marcus into next week to determine his availability to play against the Blues on Thursday night.”
The Bulldogs were forced to move the magnets in the final moments leading into their Round 1 grand final rematch with Melbourne, with Jason Johannisen a late withdrawal from the game after suffering a calf complaint during the warm-up.
Bell has revealed that Johannisen will miss at least the next fortnight of action after suffering calf tightness.
“During the warm-up for the game against the Demons, Jason had an acute episode of calf tightness,” Bell said.
“Scans have confirmed our clinical suspicion that ‘JJ’ has suffered a calf muscle strain.
“We will confirm our return to play plan over the coming days, but expect him to miss the next 2-3 weeks.”
Recruit Tim O'Brien could be in line for a spot in Beveridge's Round 2 side after completing the next step in his recovery from a hamstring injury.
“Tim successfully completed a game like rehab session last Wednesday. He ticked off full speed and acceleration and has competed a solid block of training,” Bell said.
“If he gets through our final main training session on Monday, he will be putting his hand up for selection.”
