What sports can I pick from?

We offer eight different sports that vary in availability throughout the year, found on our Sign-Up Calendar.


How much does each league cost?

League costs vary from sport to sport and estimated prices can be found on our Sports Facts Page.


When do I need to sign up by?
Leagues fill on a first come, first serve basis so the sooner you sign up the better chances of getting a spot! There is no deadline, and we'll even offer Week 2 starts when available! Don't let choosing a unique team name or finalizing your roster postpone your registration... you can edit both after you've Confirmed your team spot in the league.


How many players do I need for a Team?

Roster Cap and required gender ratios information can be found on your Captain's panel when you're inviting your teammates with the FunLink.


Roster sizes vary from sport to sport, and Underdog suggests that teams have at least one sub of each gender.  An extra couple members means more players, more fun, and more security if something unexpected comes up.  Build a full team roster for all players to be eligible for playoffs and to eliminate the chance of any forfeits due to too few players. 


If your team needs to exceed the Roster Cap for your sport, you can purchase additional roster slots for $20 per person above the cap. You can assign these additional players TeamPayer fees once added. Check out more information how to add additional roster spots below: 



How do I build my roster?

As the Captain, you can build your roster using the FunLink!

Using any app on your phone or Facebook, Twitter, or email on your computer to send your teammates the FunLink to accept their roster spot. You can also a default TeamPayer fee to your FunLink so they pay their portion of the team balance once they accept.

Rosters lock the day after the Week 2 games, so make sure your team is complete by then!


Can I create a Company Team?

Sure! Several companies offer to pay for all or part of their employee's league fees.  Please review the Company Kick-In in our Captain’s Toolbox below, or Email us about any questions regarding the set-up of your company sponsor!





Where and when do we play?

When you register for an Underdog League, you choose the location and day of the week you will be playing.  Teams usually play 5-7 regular season games plus 1-2 weeks of playoffs at the end of the season, depending on the sport.


What do I need to bring to the league?

It varies by sport.  Underdog provides most equipment, however you can visit our Sports Facts Page to check for your specific sport.  Please do wear athletic shoes and clothing!


When will I receive my team's schedule?  When will I receive the FULL season schedule? 
The first week schedule is emailed out to captains 5-7 days before the league start date.  We only do the first week schedule so that we can take into account team skill level and schedule requests before making the full season schedule, which will be posted 1-2 days after your first game.


Is it possible to make schedule requests?  What if my team can’t make our game? 

Yes!  Making a schedule request consists of asking for a change in time, date, or location of your game.  Captains can put in schedule requests through your "Manage Team" panel, you can purchase a single date request for $25 or a full season for $60.  If we are unable to accommodate the request, there will be no charge.



Any requests sent in after the full season schedule has been posted will be considered a game change and will be $50 for each change that we are able to accommodate; however, we cannot guarantee anything once the season has started.  You can send schedule requests to


The score was incorrect from our last game!  What do I do?
As a Captain, part of your responsibility is to double check the scores/standings each week after your game.  Please email with the correct score for your team's game.  We appreciate your help!





What is Team Payer?

Team Payer is an easy way for your teammates to pay their portion of the Team Balance, so you don’t have to! Send a FunLink to your teammates from your player page with a default amount input.  When a player Accepts their roster spot, they pay their portion of the Team Balance directly to Underdog, in accordance with Underdog’s Team Payment PolicyNo need for players to dig out their checkbooks or pay the ATM free before your game!


How much does each league cost?

League costs vary from sport to sport and estimated prices can be found on the Sport Facts Page!


Do I need to pay the entire Team Balance when I register?
Nope!  Captains only pay the deposit at the time of registration, which varies depending on the sport and location.  The remaining Team Balance is due the day after your first game.  Once your team has a Confirmed spot in the league, the Captain can assign dues via Team Payer to their teammates.  As your teammates Accept their roster spot, they will pay their portion and the Team Balance will reduce! 


Input a default fee to your FunLink and send it to your teammates.


Will my employer help pay for my Team Balance?

Possibly!  Check out the Company Kick-In tool in the toolbox below and see if your employer is on our list of participating companies.  If your employer is not currently partnered with Underdog, ask your HR Director to pitch in, and we’d be happy to add your company!
