Argentinian prop Juan Pablo ‘JP’ Zeiss played in Major League Rugby between 2022-2024. He represented the Houston SaberCats (2022), and the Dallas Jackals (2023-2024).

Prior to joining MLR, Zeiss had represented Los Matreros in Argentina’s URBA Top 14 since 2011, and spent 2017-19 with the Jaguares in Super Rugby. He earned 7 caps for Los Pumas between 2018-2020. Zeiss’ signing was announced in January 2022 by the Houston SaberCats and he made 14 appearances during his debut MLR season, earning 13 starts and scoring 2 tries in a season that saw the SaberCats’ qualify for the post-season for the first time in club history. Zeiss started their first Championship Series game, a 27-46 loss to the Seattle Seawolves in the Western Conference Final. He was selected in the All-MLR First XV for the 2022 season after being nominated for the MLR Team of the Week 4 times.

Following his debut MLR season, Zeiss moved up the I-45 and signed with the Dallas Jackals in February 2023. He appeared in all 16 Jackals games that season, starting 15 times and scoring 3 tries. He delivered 135 successful tackles, high for a prop. Zeiss impressed in his first season with the Jackals and was selected as part of the All-MLR First XV for 2023, the 2nd year in a row after again being selected for the MLR Team of the Week 4 more times. On 3rd October 2023 the Dallas Jackals announced the return of JP Zeiss for the 2024 season where he earned another 16 appearances (all starts) for the Jackals as they qualified for the playoffs as 4th in the West, and shocked the top-seeded Houston SaberCats (Zeiss’ former club) on the road, before falling to the Seattle Seawolves. For the 3rd season in a row, Zeiss was named to an All-MLR team, this time the Second XV.

Following the withdrawal of the Dallas Jackals from the 2025 season, Zeiss was selected 16th overall in the subsequent Dispersal Draft by Old Glory DC, but was quickly traded to the Seattle Seawolves in exchange for 2025 Salary Cap Considerations (unknown) on September 25th, 2024, the believed date of the Dispersal Draft.
