The Saints are already bad at playing defense, and things just keep getting worse.

According to Ian Rapoport of the NFL Network, the Saints believe nose tackle Brodrick Bunkley suffered a season-ending quad injury last night.

He’ll have an MRI today, but they’re clearly not expecting good news.

The veteran defensive tackle was a part of their rotation inside, and perhaps their best run defender.

Of course, it’s hard to tell, since they’ve sagged to 27th in the league in defense this year after finishing fourth in that category a year ago.
