Greg Foster, the 1984 Olympic silver medalist for the United States, died Sunday at age 64, according to UCLA track and field.

The university said Foster, a three-time world champion in the 110-meter hurdles, died peacefully at his home. He had been through a long battle with amyloidosis.

Foster had to undergo a heart transplant in 2020 due to the disease and also underwent chemotherapy.

Foster excelled on the UCLA Bruins from 1977 to 1980. He was instrumental in helping UCLA win the 1978 NCAA title and win the 110-meter hurdles individual title that year and in 1980. He also won the 200-meter hurdles in 1979.

Foster’s 13.22 second finish in the 110 meter hurdles in 1978 remains a UCLA record and stood for decades.

Ato Bolden, a four-time Olympic medalist and current track and field analyst for NBC Sports, recalled Foster on Twitter.

«UCLA Bruin legendary 110m hurdler Greg Foster passed away tonight,» he wrote. «He was world champion in 1983, 1987 and 1991, and Olympic silver medalist in 1984, in Los Angeles. Our deepest condolences to his family and friends. The world of track and field mourns this legend of obstacles.»

Foster ended up surpassing his UCLA record in the 110 meter hurdles in 1981 when he ran 13.03 seconds. However, his rival at the time, Renaldo Nehemiah, who also won a Super Bowl with the San Francisco 49ers, beat him by 13 seconds.

But once Nehemiah left the road to pursue his soccer career, Foster entered the 1984 Olympics, with the world’s four fastest times that year.

When it came time for the 110m hurdles final at the Olympics, Foster was eventually beaten by fellow American runner Roger Kingdom, who finished three-hundredths of a second faster than Foster, who had a shaky start to the block.
