Slavisa Jokanovic's side were one of the favourites at the start of the season among bookies to get promoted, but only four wins in 16 games, including a winless October, have seen their odds drift heavily.
Currently sitting in 17th, SkyBet are offering odds of 100/1 for the Whites to win the division, while Brentford are being offered at 66/1 - a massive difference from the start of the season where Fulham were favoured more than the Bees.
Jokanovic's side are now also 11/1 to get promoted from the division, while they're 16/1 to win the Play-offs, with Brentford at 8/1 to get promoted and 12/1 to win the end of season showpiece.
QPR , meanwhile, 500/1 to win the league, 50/1 to get promoted and 50/1 to win the Play-offs.
Meanwhile, Fulham's attacking woes are clear for the bookies to see too - they're offering huge odds of 50/1 for Aboubakar Kamara to be the league's top scorer, while Rui Fonte is double that at 100/1.
And if you fancy a Fulham vs Brentford west London derby Play-off final, you can get that at odds of 100/1.
