LONDON (AP) - Steven Lopez turned an ankle in practice two weeks ago. Diana Lopez has been dealing with an injured left knee for months.
Family secrets - until they were revealed at the London Olympics.
Not only was there no taekwondo gold for the Lopez clan in London, there might not be any medal.
A day after his Diana lost her first-round fight, Steven, her brother, fell in his opening bout in the men's under-80-kilogram division Friday, ending his hopes a third Olympic title.
For the first time since the Korean martial art became a medal sport at the Olympics in 2000, the Lopezes may go home empty-handed.
"You work a lifetime for these moments," said U.S. coach Jean Lopez, older brother to Steven, Diana and Mark Lopez, himself a former silver medalist and the team's training partner. "But it's been unusual circumstances that we've had to deal with."
The full extent of the injuries was not revealed before either Steven Lopez or Diana Lopez fought, their brother and coach not wanting to give any opponent a competitive edge.
Steven Lopez lost an 1-0 lead and was beaten 3-2 by Ramin Azizov of Azerbaijan, No. 1 seed in the under-80-kilogram field. If Azizov makes the gold-medal match, Lopez would compete in the consolation round, or repechage, and have a chance at bronze.
That is, if his brother lets him fight.
Jean Lopez said he was considering not allowing his brother to compete in the repechage if he even qualifies, saying the ankle is so bad that Steven Lopez "can barely walk."
"I'm going to have to make a tough decision," Jean Lopez said, adding that the injury got worse on Friday.
The Lopez family has won five medals at the Olympics - gold for Steven in 2000 and 2004, a silver for Mark at Beijing in 2008 and bronzes for Steven and Diana four years ago.
But this trip has been difficult, with injuries compounding losses.
"At one moment I heard a pop," Diana Lopez said Friday. "So that's when I knew."
There's some confusion as to what exactly exacerbated Diana Lopez's injury when she fought Thursday.
She tore a ligament in her left knee in 2009, never had surgery, and about three months ago began dealing with a suspected torn meniscus. Jean Lopez said she "definitely dislocated" the knee warming up before her first-round fight Thursday, while Diana Lopez said the "pop" came in the second fight, her repechage match against Finland's Suvi Mikkonen.
"In my first fight against China, I knew I wasn't 100 percent with my knee of course, but I wasn't going to make any excuse," Diana Lopez said Friday, walking with a slight limp and with her knee heavily wrapped. "But going into my Finland fight, that's when I knew my knee was (shot)."
Diana Lopez, whose first-round loss in the women's under-57-kilogram bracket came to eventual silver medalist Hou Yuzhuo of China, said she will have an MRI exam on Saturday at the Olympic Village to determine the severity of the injury.
Steven Lopez, like his sister, was unseeded at the London Games, which meant a tougher-than-expected first-round opponent. The draw for the Olympics was based in large part on the world rankings, and the Lopez family tends not to participate in many international events - the ones that play the biggest role in the ranking system.
Jean Lopez said the first thing his brother did after losing Friday was apologize for letting him down. Jean Lopez said it was unneeded.
"I never put myself in the position mentally to not go in there with 100 percent belief that we won't find a way to win," Jean Lopez said.
