Sochi, Russia (SportsNetwork.com) - American skater J.R. Celski failed to qualify for the semifinals of the men's 1,000 meters short track event on Saturday following a crash in the last of four quarterfinal heats at the Iceberg Skating Palace.

Celski, winner of two bronze medals at the 2010 Vancouver Games, will remain without a medal in Sochi after slipping around a turn and crashing into the sideboards. Sin Da Woon of South Korea won the fourth heat and Russia's Semen Elistratov finished second to earn places in the semifinals.

The semis and final round of this event will both take place on Saturday.

Chris Creveling and Eduardo Alvarez of the United States also failed to make it to the semis. Alvarez crashed in the third heat, which also saw Canadian Charles Hamelin, winner of the 1,500 in Sochi, slip and fall out of medal contention.

Hamelin lost his footing around a turn and appeared to take out Alvarez. Both skaters got up and finished the race, but were well behind Russia's Viktor Ahn and Sjinkie Knegt of the Netherlands.

Ahn is after his sixth Olympic medal on Saturday. He won bronze in the 1,500 on Monday.

Also moving past the quarterfinal stage were China's Han Tianyu and Wu Dajing, Russia's Vladimir Grigorev and Lee Han-Bin of South Korea.
