Goaltender Privileges

Question to me via email:

Goalie is excluded, and field player takes the cage in the "man-down" series.  Shot is taken and the defensive field player (who is playing in the goalie position) comes out of the water, both arms extended outward, and he blocks the shot, but only with 1 arm.  However, again....the point here is (s)he uses body and two arms to shield the cage prior to blocking the ball with only 1arm

Some relevant rules:

WP 21.6    To attempt to play or block a shot with two hands outside the 5 meter area.  (this is an exclusion foul)

WP 21.17    For the defending goalkeeper to fail to take up the correct position on the goal line at the taking of a penalty throw having been ordered once to do so by the referee. (this is an exclusion foul) Another defending player may take the position of the goalkeeper but without the goalkeeper’s privileges or limitations.

WP 22.2    For a defending player to commit any foul within the 5 meter area but for which a goal would probably have resulted.
    [Notes.  In addition to other offenses preventing a probable goal, it is an offense within the meaning of this Rule:
(a)    for a goalkeeper or other defending player to pull down or otherwise displace the goal (figure 20);
(b)    for a defending player intentionally to play or attempt to play the ball or block a shot with two hands (figure 21);
(c)    for a defending player intentionally to block or attempt to block a pass with two hands;
(d)    for a defending player to play the ball with a clenched fist (figure 22);
(e)    for a goalkeeper or other defending player to take the ball under the water when tackled.

Taken together, this means that this field player does NOT have the privileges of a goalkeeper so the "attempt to play the ball or block a shot with two hands" in the penalty area constitutes a penalty foul.
