AR 7-3-4-V

Eligible receiver A44 is running a pass pattern near the sideline. As
a legal forward pass comes toward him, he accidentally steps on
the sideline, leaps, muffs the pass into the air, returns to the ground
inbounds, grabs the ball and lands on his knees inbounds with the
ball firmly in his possession.

RULING: Illegal touching. Penalty— loss of down at the previous spot.
