Just a few days ago, Hugh Jackman, the actor who plays Logan aka Wolverine in the "X-Men" franchise, teased fans about the Berserker Rage and the possibility of Victor Creed or Sabretooth appearing in the final solo movie "Wolverine 3."

And recently, Liev Schreiber, the actor who played Victor Creed in the previous "Wolverine" movie, fuelled speculations more when he replied to Jackman's tweet.

On Aug. 17, Jackman took to Twitter to share an image of him working out. He captioned the photo, "Let's do this! How's with me!? #WOLFPACK vs. #DOGPOUND"

Schreiber then directly tweeted Jackman, which ignited more hype for the final solo movie of "Wolverine." Schreiber's teasing was pretty vague, but it was enough to fuel fans' speculations. He wrote, "do I have to do that..."

Fans are advised not to jump into conclusions just yet, but considering Jackman just dropped the name Sabretooth during his podcast with Sydney Confidential via Screenrant, it wouldn't be surprising to see everyone hyped up by the teasers provided by both actors.

According to Cinemablend, the actor did not say or announce the reason why he has to work out. However, fans have already assumed that this is for his upcoming final solo movie "Wolverine 3," whose storyline, until now, is still being kept under wraps.

There are a couple of speculations though due to a different teaser Jackman gave fans during the San Diego Comic-Con. The actor teased the "Old Man Logan" story arc in the "X-Men" comics which features a very old and retired Wolverine and Hawkeye, as well as other surviving heroes in the Marvel universe during that time.

All of these are simply speculations though, so it's best to take them with a tiny spec of salt for now, as the film "Wolverine 3" isn't due to be released in cinemas until March 3, 2017.
