With the release of the revamped Overwatch League website over the weekend, last-minute roster additions for the Boston Uprising and Seoul Dynasty became public. Additionally, there were questions raised about sado of the Philadelphia Fusion.

The Boston Uprising added a pair of supports to bolster their roster. The additions were Avast, most well-known for his time on LG Evil, and Neko, the flex support for Apex Season 4 fourth place finishers RX Foxes.

The Seoul Dynasty picked up an additional Lunatic-Hai player in Bunny, a DPS player who played for the organization's APEX Challengers team and previously most notably for the defunct BK Stars. Seoul Dynasty also picked up MVP Space tank KuKi.

The team page for the Philadelphia Fusion has sado listed, however a video on the website that lists every team's roster did not include him. While it is possible that this could just be a mistake, his omission is curious given the backlash against his inclusion on the Fusion roster. Blizzard and OGN have both administered bans against sado previously after he was accused of boosting in Korea.

Team rosters will be locked until a mid-season signing period takes place. There were no last-minute signings to the league's smallest rosters: the seven-person roster of the Los Angeles Gladiators and the six-player roster of the Florida Mayhem.
