"Batman v Superman" star Henry Cavill is back at it again. In a new Instagram post, he once more teased the arrival of Green Lantern, long before the Emerald Crusader's solo adventure in 2020.

Cavill's post is more or less a selfie of himself working out. In the caption, he explains that he had a knee injury and that he's glad to get back into his workout routine. However, following his sentiment about injury and recovery, he namedrops the fan-favorite DC character: "Nothing funny to post here, it's deadly serious because I've got to make sure that I'm bigger than Green Lantern....Wait whaaat?"

Since I came off the ol knee injury I've been steadily increasing my training work load. I know it's irritating when people say this but it genuinely does feel so good to be back in it. I'm not destroying myself every day. Just working towards improvement by pushing hard enough to elicit change. Nothing funny to post here, it's deadly serious because I've got to make sure that I'm bigger than Green Lantern....Wait whaaat?

This isn't the first time Cavill teased Green Lantern. Earlier this month, he posted two new photos with the caption "Kal looking for Hal" and the hashtag #GreenLantern. It’s possible, and most likely, that Cavill is just having a bit of fun on Instagram; however, he has stuck hard with these Green Lantern references, which may suggest that there's a hint of truth to his teasing. Whether or not that means Hal Jordan will show up in "Justice" League is yet to be seen.

It’s been a year and a half since WB announced the “Green Lantern Corps” movie, and there have been no major announcements about the film since. The film is right now slated to hit theaters in 2020, which is still a ways off, but Green Lantern himself might appear in “Justice League 2.”

Arriving November 17, “Justice League” stars Ben Affleck as Batman, Henry Cavill as Superman, Amy Adams as Lois Lane, Gal Gadot as Wonder Woman, Jason Momoa as Aquaman, Ezra Miller as The Flash, Ray Fisher as Cyborg, Willem Dafoe as Vulko, Jesse Eisenberg as Lex Luthor, Jeremy Irons Alfred Pennyworth, Diane Lane as Martha Kent, Connie Nielsen Queen Hippolyta, and J.K. Simmons as Commissioner Gordon.
