Nate Ebner

Traditionally Olympic stars have tried the NFL after competing for medals, but this year in Rio, it was the opposite.

Nate Ebner, a Patriots safety since 2012, became the first active NFL player to participate in the Olympics as the team allowed him to represent the U.S. in rugby. Jahvid Best, who played running back for two seasons with the Lions, competed in the 100 meters for Saint Lucia, a island nation in the Caribbean. Best's dad has dual citizenship.

Here's a look at athletes who have been in the Olympics and the NFL. This is not a comprehensive list -- anyone remember Giants quarterback Randy Dean competed in handball for the U.S. at the 1976 Montreal Olympics? -- but gives you a good sense that success in one sport doesn't necessarily translate to pro football.

Bob Hayes

Bob Hayes

At the 1964 Olympics in Tokyo, Hayes won gold medals and set world records in the 100 meters and the 4x100 relay. He played for the Cowboys for nearly a decade (and one season with the 49ers). He won a Super Bowl, became a three-time Pro Bowler and a two-time All-Pro on his way to the Hall of Fame.

Jim Thorpe

Jim Thorpe

At the 1912 Olympics in Stockholm, Thorpe won gold in the pentathlon and decathlon but was stripped of his medals a year later, when it was discovered he had been paid for athletics in the United States, and was not an amateur. The International Olympic Committee officially restored his medals in 1983, 30 years after his death. Thorpe played pro football, baseball and basketball, and was the first president of the American Professional Football Association, the forerunner to the modern NFL.

He remains the only athlete to win an Olympic medal and a Super Bowl in the same season. Carter's daughter, Michelle, won gold in the shot put in Rio.

Herschel Walker

He went on to play two games as a receiver for the Bengals, catching one pass for 41 yards.

Ollie Matson

In his 14-season career, Matson was a six-time Pro Bowler and seven-time All Pro. When he retired, he was ranked second in career all-purpose yards, with 12,799, trailing only Jim Brown. In 1972, he was inducted into the Pro Football Hall of Fame.

Hines was drafted by the Dolphins in 1968, but struggled to succeed, even earning the nickname "Oops" for his lack of skill. In 10 career games with the Dolphins and one with the Chiefs, Hines caught just two passes for 23 yards.
