Looks like the ship is taking on water.

The ratings are in for episode seven of The Ultimate Fighter (TUF) 13 and they aren't pretty. According to numbers released today by Spike TV, the latest episode garnered a 0.8 household rating (including a 0.90 in males 18-49 as well as in males 18-34) for an average audience (and season low) of 1.0 million viewers.

Even opposite the NBA playoffs on TNT, which averaged a 5.04 in males 18-34 and 6.8 million viewers (peaking with 10.8 million viewers in the final 10 minutes), that number is considerably low for the TUF series.

And it may get worse before it gets better.

That's because the ailing Lesnar recently pulled out of his UFC 131 headliner against opposing TUF coach Junior dos Santos, giving viewers little reason to invest in the remaining three episodes. We still have a welterweight elimination to get through but if these ratings are any indication, it may not be enough.

Here's how the numbers stack up to date:

Episode 1: 1.5 million viewers
Episode 2: 1.2 million viewers
Episode 3: 1.3 million viewers
Episode 4: 1.3 million viewers
Episode 5: 1.5 million viewers
Episode 6: 1.2 million viewers
Episode 7: 1.0 million viewers

Seven episodes down, three to go.

TUF 13 episode seven saw Chuck O'Neil battle his way back into the competition by submitting Javier Torres in their wildcard bout.

And Len Bentley did a lot of complaining.
