OK. This should be an easy one for the refs out there. It's been awhile since I reffed. Situation: Team A player plays long ball to edge of Team B box parallelling the sideline. Keeper for Team B goes outside penalty area and with his feet carries it back into the area, then picks up the ball. Ref blows whistle and rules indirect free kick and if it were a handling of a back pass, even though no other Team A player touched the ball. I thought this was a legal play. What's the answer? thx in advance.
