The Norte Vista Braves were on their way back from a soccer game in the
High Desert. It was about an hour’s drive in the old yellow school bus and
this ride was unusually quiet. The Braves had lost a tightly contested
game. Everyone was a little down because this game changed the league
standings and may have cost them a seat in the playoffs.
Courtney, the starting goalkeeper for the Braves, received a hard hit to
the ribs during the last minutes of the game. She never complained much
and today was no exception. Ned, the team’s athletic trainer, saw what
happened and checked her out before she got on the bus. He determined
that she might have a contusion on her rib or possibly even a fracture, so
he wrapped it up and put ice on the area to control the swelling and
reduce the pain. Courtney blamed herself for the loss and was pretty
upset. She just wanted to be alone in the back of the bus. Ned told the
girls around her to keep an eye on her during the ride home.

About 30 minutes into the trip, Megan, who was sitting next to Courtney,
yelled for Ned. Something was wrong with Courtney. Ned rushed to the
back of the bus to check on her. She was breathing very fast and felt cool
and clammy. Then she passed out.
When traveling, what seating arrangements might be appropriate for an
injured player? What do you think was wrong with Courtney? What would
you do for her? Can you create an emergency action plan for travel
emergencies such as this?
