Roughead had been in some doubt to take part in the 2016 premiership decider due to bleeding in his eye as a result of being hit in the face by the ball during the Dogs' stirring six-point victory over Greater Western Sydney in last weekend's preliminary final.

The 25-year-old took no further part in the match after leaving the ground in the second quarter.

However, he has recovered well from the unique injury and performed strongly at the Bulldogs' main training session on Thursday in front of some 10,000 diehard fans at Whitten Oval.

The green light for Roughead all but ends big man Tom Campbell's slim hopes of facing Sydney in the grand final.

Campbell's fellow emergencies are Lin Jong and Matthew Suckling. At this stage, the Dogs will take their first unchanged line-up into the weekend for the first time since Round 2.

Having already broken their 55-year grand final drought, the Bulldogs are now aiming to win their first premiership since 1954 and end the league's longest active premiership drought.

This will be just the third grand final the Dogs will feature in since their entry into the competition in 1925.
