(CNN) - With a shot at high school state championship glory on the line, a Jewish basketball team in Texas is opting for the sidelines, aiming for something a little higher.

The Robert M. Beren Academy in Houston will forfeit its semifinal playoff spot in the Class 2A basketball championships this weekend because the game falls on a Friday night, the start of the Jewish Sabbath.

The private Orthodox Jewish school observes the weekly Jewish day of rest, called Shabbat, from sundown Friday to sundown Saturday.

"You get put in adversity and the way you handle things says a lot about your character. So this is an opportunity to show our character," Chris Cole, coach of the Beren Stars, told CNN Houston affiliate KPRC.

The playoffs for the Texas Association of Private and Parochial Schools (TAPPS) are set for this weekend. Beren Academy's semifinal game and the championship game are both scheduled during the Sabbath observance.

"If we give up this opportunity for our religion it just shows how much we deeply care for it," Isaac Buchine, a player on the Beren Stars, told KPRC.

"We are hopeful that the TAPPS league will move the games a few hours so that we can compete," the school said in a statement posted on its website.

"This is a testament to our school and to Coach Cole for his support and dedication, that, independent of the desire to compete, is the desire to uphold our Jewish values,” the statement continued. “We are proud of who we are, and have the courage to act accordingly."

By Wednesday, more than 5,000 people had signed an online petition, supported by the school, to move the Beren Stars’ semifinal game to Friday morning.

Over the weekend, school officials appealed to the league to find another time for the game, but the league said in a statement Wednesday the appeal was unanimously voted down by the league's nine-member board.

Cole is holding out hope that the TAPPS board will change its mind and reschedule the Stars’ games.

The Jewish observance of the Sabbath comes from the book of Genesis. In the week-long creation story, God creates the world, and all that is in it, in six days. After seeing that it is "very good," God rests on the seventh day.

How Jews practice that rest varies, but in Orthodox sects, it often means no working, driving or cooking. Many observant Jews also attend religious services on Shabbat.

Observance of the Sabbath can pose a challenge for observant Jews living in a culture on a different timetable.

Yuri Foreman , a champion boxer and rabbi in training, postponed a major fight in 2010 because it fell on a Saturday night. He took the ring once the sun went down.

U.S. Sen. Joe Lieberman, a Connecticut independent, has been known to walk miles to his Washington home when votes on the Senate floor run into Friday night.

Lieberman wrote a book about Shabbat and told CNN's Belief Blog last year the stringent rules around the observation serve an important part in preservation of the Jewish faith.

Founded in the late 1970s, the TAPPS league is made up of 220 schools. In a statement posted on its website by the TAPPS executive board, the league said at the time of its organization, no member schools observed the Sabbath on Saturday. At the same time, the bylaws forbid games on Sunday, a nod to Christian Sabbath observance.

The league statement also said Beren Academy first met with league officials in June 2009 to discuss joining TAPPS.

"At that time, the Board pointed out that TAPPS schedules its team sports championship on Fridays and Saturdays, which would conflict with Beren’s observation of their Sabbath,” the statement said. “The Board pointed out that the posted schedule for the state tournament would be followed and no changes made, unless weather related or similar conditions existed."

The league also pointed out another rule in its bylaws stipulating that if a team cannot follow the playoff schedule, it is up to the school to remove itself from the playoffs.

Our Lady of the Hills School in Kerrville, Texas, will take Beren Academy's spot in the playoffs Friday night, the league said.
