2008: 3-1-1
First and Third Periods
ARTICLE 1. Each half shall start with a kickoff. Three minutes before the scheduled starting time, the referee shall toss a coin at midfield in the presence of not more than four field captains from each team and another game official, first designating the field captain of the visiting team to call the coin toss. Before the second half, captains will meet with the referee to select second half options.
During the coin toss, each team shall remain in the area between the nineyard marks and its sideline or in the team area. The coin toss begins when the field captains leave the nine-yard marks and ends when the captains return to the nine-yard marks.
PENALTY—Five yards from the succeeding spot [S19].
a. The winner of the toss shall choose one of the following options for the first or second half at the beginning of the half selected:
1. To designate which team shall kick off.
2. To designate which goal line his team shall defend.
b. The loser shall choose one of the above options for the half the winner of the toss did not select.
c. The team not having the choice of options for a half shall exercise the option not chosen by the opponent.
d. If the winner of the toss selects the second-half option, the referee shall use [S10].
For 2009 and beyond: I submit that it is still there, although not explicitly. If the team winning the toss does not choose option 3, then they are implicitly giving the second half option to the team who lost the toss.
