Dudi Sela, Israel's # 1 player quit his quarterfinal match in the third set of the 2017 Shenzhen Open so he could begin observing Yom Kippur—the holiest day of the Jewish year—by the time the sun set, forfeiting a possible $34,000 in prize money and 90 rankings points.[1][2] He had asked the tournament organizers to have his match be moved forward to be completed before sunset to accommodate his religion, but they denied his request.[1][2]
