Goodwin, a 2013 third-round draft pick of the Bills, competed in the long jump at the 2012 Summer Olympics in London.
According to the Sports Illustrated report, which cited a USATF official, Goodwin was added to this week's championships by petition based on his history in the sport.
At least a top-three finish and an 8.10-meter long jump would qualify Goodwin for the World Championships in Beijing on Aug. 22-30. Goodwin would almost certainly have to miss practice time and possibly preseason game action with the Bills to compete in that event.
Goodwin's splitting time between football and track wouldn't be unprecedented in the NFL. Former running back Jeff Demps, who also competed in the 2012 Olympics, skipped the NFL scouting combine and draft in order to run track.
Goodwin enters a critical training camp in which his roster spot could be in jeopardy. The speedy Texas product had just one reception last season in 10 games, losing his kick-returning duties to midseason addition Marcus Thigpen.
The Bills' signing of Percy Harvin this offseason also puts pressure on Goodwin, who has battled several injuries in his first two NFL seasons.
"A lot of the injuries I had were very minor and it was kind of blown up a little bit," Goodwin said this spring. "But part of that has to do with me being in the training room so often. The nagging injuries, I've just got to suck it up and play through it."
After Goodwin was shaken up on a play late in practice last week, coach Rex Ryan wasn't surprised to see the 5-foot-9, 179-pound receiver was slow to get up.
"No, I have seen him do this a few times," Ryan said. "You know he is all right. I looked at him. He is OK."
