Here are the Week 18 underdog picks

We're down to the last day of the regular season in American pro football, and the standings in our charity underdog game are as tight as ever. A mere 4½ points separate first place from fifth, and even our 11th-ranked player is just 10 points from the top. Only the top three finishers will win bucks for their favorite eligible charities when we wrap things up on January 26.

Clearly today's games could be crucial. And here's what our players have predicted for the weekend – the mutts, in caps, to win outright:

17.5  CLEVELAND at Baltimore (Saturday, unsuccessful) - Stephen F., SteveO, Linda

13.5  NEW ORLEANS at Tampa Bay - Kosar19

10  KANSAS CITY at Denver - Bad Picker, Buster Dog-las, Annie B., Meow, Mojo, Andypdx, PDXileinOmaha, Cliff

IMPORTANT NOTE: This post has been updated with all picks for the week.

Players, a heads-up about next week and the week thereafter: For those two weeks, all picks will be due early Saturday, rather than on Sunday. The exact time, not yet announced by the league, will be posted here Tuesday with the lines.

But first things first: Good luck to everyone with a 'dog in the hunt today!
