accidental offside touch

[Robert Goodman]

A player in the opponent's half of the field is offside when a teammate passes the ball forward, aiming at another teammate. The offside player is not looking at the ball when it's played but at a linesman or opponent in the other direction, to see where he has to get to to get onside, and is moving toward his own goal line when he runs into the ball.

(1) The ball just grazes him as it continues into space where its intended receiver runs onto it. Looks like promising attacking play, but no better than if the offside player's touch had not occurred.

(2) The ball makes solid contact with the offside player and bounces back toward his team's goal line, and his team regains control of it.

What's the call in each case?
