Surprise! Lolo Jones competes in hurdles at US Olympic track and field trials

EUGENE, Ore. — Lolo Jones finished last in the fourth heat of the women’s 100-meter hurdles Friday night at the U.S. Olympic track and field trials at Hayward Field and no, you have not taken a time machine back to 2008.

Despite her last-place finish, Jones advanced to Saturday's semifinals along with reigning Olympic silver medalist Keni Harrison, who finished first in the heat at 12.49. Due to the high number of scratches in the women's 100-meter hurdles, all competitors in the heats advanced.

"If I wake up tomorrow and don’t need my cane, we’re going!" Jones said after her heat.

From NFL plays to college sports scores, all the top sports news you need to know every day.

At 41, Jones is now old enough to compete in track and field masters meets. She once held the best time in the world in the 100 hurdles and was a favorite to win gold at the 2008 Beijing Games before she clipped the second-to-last hurdle and finished seventh. Desperate to win an Olympic medal, she later took up bobsled, and competed in the two-woman bobsled at the 2014 Winter Olympics in Sochi.

Of everyone who ran in the women’s 100 hurdles, Jones easily got the biggest cheer from the Hayward Field crowd.

Harrison, who has the 20th fastest time in the world this season, finished with the fourth fastest qualifying time. Masai Russell recorded the best time of the day (12.35), followed by Alaysha Johnson (12.37), Tonea Marshall (12.41) and Harrison.

Nia Ali, the 2016 Olympic silver medalist and the 2019 world champion, finished last in the third heat, telling NBC that she made a last-minute decision not to push it since everyone would automatically advance.

"My warmup didn’t go as planned," said Ali, who had the sixth fastest time in the world coming into the trials. "I knew that everybody made it through. …I did what I had to do."

The final is scheduled for Sunday at 8 p.m (5 p.m. local).
