If a player contacts an opponent while the disc is in the air and thereby interferes with that opponent's attempt to make a play on the disc , that player has committed a receiving foul. Some amount of incidental contact before, during, or immediately after the attempt often is unavoidable and is not a foul.

If XVI.C.2.b.1 of the continuation rule applies: if the call is uncontested, the fouled player gains possession at the spot on the playing field closest to the spot of the infraction. If the foul is contested, the disc reverts to the thrower.

The Principle of Verticality: All players have the right to enter the air space immediately above their torso to make a play on a thrown disc. If non-incidental contact occurs in the airspace immediately above a player before the outcome of the play is determined (e.g., before possession is gained or an incomplete pass is effected), it is a foul on the player entering the vertical space of the other player .

Force-out Foul: If an airborne player catches the disc and is contacted by an opposing player before landing, and that contact causes the player to land out-of-bounds instead of in-bounds, or out of the end zone instead of in the end zone, it is a foul on the opposing player and the fouled player retains possession at the spot of the foul. If an uncontested force-out foul results in an in-bounds player landing outside the end zone being attacked when they would have landed in the end zone without the foul, a goal is awarded.
