With two substitutions, 11+2 = <<11+2=13>>13 players from the team played the game in the first half.
In the second half, the team made twice the number of substitutions it made in the first half, a total of 2*2 = <<2*2=4>>4 substitutions.
The total number of players who played the game is 13+4 = <<13+4=17>>17
If the soccer team had 24 players prepared for the soccer game, the number of players who did not play the game is 24-17 = <<24-17=7>>7 players.
