December 27-29, 2016
Orlando, FL*The ODP Events listed above are for ODP Region IV teams/individuals only. Individuals competing on club teams at these tournaments are not identified as ODP players and therefore are NOT allowed to participate accodring to CIF Rules."
"According to the CIF State and Southern Section clarifications andstaying with the long history of the ODP and CIF exemption, ONLY ODP roster players for the specific tournament are allowed to play forboth high school and ODP teamsduring the same season. This has always been accompanied with letters from US Youth Soccer (ODP)for the individual players to present to their schools and coaches. If a student-athlete is notinvited and are not placed on the specific ODP roster for the December/January Disney Showcase tournaments(or any tournament- including CRL gmaes) as an ODP player, they areNOT exempt and may NOT play for the high school and then for a club team in the tournament. We encourage allhigh school coachestobe careful with this issue. SCHSSCA wants to remind all Southern Section coaches: any student-athlete that plays in December for theirhigh school, who then attends the Disney Showcase and plays for their club team, is in violation of CIF rules and will cause the player to sit out more games in January (2:1 ratio)as well as cause the high school team to forfeit any games the said player competed in previously.
