NFL teams unanimously voted in favor of modifications to the catch rule for the 2018 season on Tuesday at the league's owners meetings in Orlando, Fla.
The new rule says that a ball is deemed a reception when the player has control of the ball, two feet down (or another body part), and makes a football move. A football move is defined as either a third step, reaching/extending for the line to gain, or the ability to perform such an act -- with on-field officials being required to judge whether it occurs.
