The women, both flight attendants on the plane, filed the lawsuit Friday against Brandon McManus, a kicker for the Jacksonville Jaguars at the time of the alleged incidents.
Mr McManus has denied the allegations.
The Jaguars said they were aware of the complaint and acknowledged “the significance of the claims”.according to BBC.
Mr McManus and the rest of his team were on a flight from Jacksonville, in Florida, to London to play in an NFL game when the alleged incidents occurred.
In the lawsuit, obtained by ESPN and not yet posted on the local county’s public records database, the women say Mr McManus rubbed himself against them and grinded against them during the 28 September 2023 flight.
One of the women alleged Mr McManus tried to kiss her while she was seated during a period of turbulence.
They are asking for more than $1 million and a jury trial.
