(DENVER, CO = Won Joeng) The Colorado Mammoth announced their 2025-26 training camp roster this week, signaling the start of another season of high expectations in the National Lacrosse League (NLL). The four-week camp kicks off Oct. 30 at Foothills Fieldhouse in Lakewood, Colorado, as players compete for 25 coveted roster spots.

The Mammoth open the regular season on Nov. 29 at Rogers Arena against the Vancouver Warriors, followed by their home opener on Dec. 27 at Ball Arena, where they’ll face the Georgia Swarm in a New Year’s celebration of lacrosse at the LOUD HOUSE.

New Faces and Returning Leaders

This year’s camp roster features 17 new players, including six 2025 NLL Entry Draft selections. Returning veterans such as Dillon Ward, Robert Hope, Ryan Lee, and Jordan Gilles will lead the charge as the Mammoth seek to reclaim championship form.

Among notable positional changes, Owen Rahn, who debuted as a defenseman last season, is expected to join the forward group after showing impressive agility and offensive awareness in transition play.

Camp Schedule and Preseason Matchups

The four-week camp begins with team introductions and dinner on Thursday before training officially starts Friday morning. The first 72 hours will include conditioning, media day activities at Ball Arena, and medical evaluations as players reunite and adjust to the intense competition.

Week two will see the Mammoth travel to Six Nations, where they’ll hold joint practices and a preseason scrimmage against the Halifax Thunderbirds. The third week features a stop at the Toronto Rock Athletic Center for additional sessions and a matchup with the Toronto Rock.

The final week concludes on the West Coast, where Colorado will face the Vancouver Warriors in their last scrimmage before the final roster cuts on Nov. 24.
