[12] In response to the ongoing COVID-19 pandemic, the PUL elected to hold a limited 2021 competition season with games occurring across three weekends in August 2021 in New York,[13] Milwaukee,[14] and Portland, Maine.

[15] With three teams competing at each event, the Raleigh Radiance,[16] Milwaukee Monarchs,[17] and Medellin Revolution[18] emerged victorious.

[20] In December 2022 it was announced that Medellin would be leaving the PUL to join a new Latin American league,[21] and that they would be replaced by the Philadelphia Surge.

[22] In November 2023 it was announced that Columbus would be leaving temporarily, and the remaining teams would be redistributed into two divisions, North and South.

[23] After the 2024 season it was announced that the Los Angeles Astra, formerly of the Western Ultimate League, would be joining the PUL.

In the 4th quarter and overtime (which lasts 4 minutes), play ends when the result of the throw is determined once the clock hits 0:00.

[27] Observers actively call up/down, in/out of bounds or end zone, offsides, and delay of game infractions.
