American figure skater Mirai Nagasu made history on Monday as the first American female (and third ever) to land a triple axel during Olympic competition.

According to earlier reports, the 24-year-old stunned the crowd in Pyeongchang, South Korea, with the jump, which requires the skater to spin three three-and-a-half times in the air before making a difficult landing on the opposite foot.

Despite the challenge, Nagasu appeared to land the jump with ease.

While most viewers were busy concentrating on the skater's historic performance, many couldn't help but notice something peeking out from Nagasu's bright red costume.

According to Yahoo Sports, some viewers thought that she had a large “USA” tattoo on her leg, while others thought it might be some sort of bruise.

Some Twitter users were perplexed by the mark. They wrote:

However, most of the guesses came up short.

The mark on Nagasu's leg wasn't actually a tattoo or bruise at all, but an elastic sports tape that is meant to ease pain in athletes' muscles, Time reports.

It's called kinesiology tape, and Nagasu herself cleared up the rumors for good after her amazing performance.

In a tweet, she confirmed it was “just some tape.”

It seems the 24-year-old won't be repping her country with a massive tattoo any time soon, but it certainly seems she's helping lead the U.S. to victory.
