— -- "Game of Thrones" star Kit Harington was photographed at a Wimbledon tennis match in London this past Thursday -- but the big story seemed to be his hair.

In the photo, Harington is back to sporting his familiar long hair, after showing up at the U.K. premiere of the movie "Testament of Youth" back in January with a much shorter 'do. That's led to speculation that his "Game of Thrones" character, Jon Snow, may be returning to the popular drama.

Snow was killed off during last month's season-five finale.

Harington and the show's producers have denied the rumors in the past, but after the finale, co-star Emelia Clarke hinted at Snow's possible return, telling MTV, "If I had to bet, I would say it's a 50/50 chance. There are some helpful people there, who could bring Jon back to life."

The 28-year-old actor's hair has created a lot of excitement on social media. "This is a recent picture of Kit Harington, notice his hair. He hasn't cut it. JON SNOW LIVES," tweeted one fan.

Another post reads, "Kit Harington still hasn't cut his hair, y'know what that meeeaaaaaaannssssss (-:"
