ARE Port Adelaide contenders or pretenders? And have the wheels fallen off at Melbourne?
Two massive questions that might be answered at the conclusion of Thursday night's monster clash between the Power and Demons at Adelaide Oval.
FOLLOW IT LIVE Power v Demons from 7.10pm ACST
After winning its first nine games, Melbourne has suddenly lost top spot on the back of a disastrous three weeks that has seen seen the one-time premiership favourites lose to Collingwood and Greater Western Sydney.
The Demons haven't kicked more than 10 goals in that stretch and will be hoping star recruit Ben Brown can get the forward line firing as he returns for his first game since round nine.
The Power are riding a three-game win streak, but have yet to claim a top-four scalp with losses to Geelong, Western Bulldogs, Brisbane and West Coast raising questions about their premiership credentials.
In a massive boost at selection, influential young gun Zak Butters will return for his first game since round four, while important defender Tom Clurey is also back.
A healthy victory could see the Power leapfrog the Demons into second place with Melbourne a chance to drop out of the top four by the end of the round if Brisbane and Geelong also win.
This is a MASSIVE clash with huge top-four ramifications.
