Hulk Hogan remains a free agent following the expiration of his contract with TNA Wrestling last month and the two parties being unable to reach a new agreement. This afternoon on Facebook, the legendary grappler teased a possible return to WWE by publishing the photo below of himself clutching a replica copy of the WWE Championship. His caption reads, "Thinkin, thinkin, thinkin. HH."

It was reported last week by that the 60-year-old has been "training like a mad man" in hopes of wrestling again for WWE.

Hogan returning to the promotion could hinge on Triple H, who is leaving the door open for his return to the sports-entertainment organization. The six-time WWE Champion told the Associated Press earlier this month that he was warmly received by Vince McMahon's son-in-law at a recent charity function.

"He just welcomed me with open arms. He said if ever I decide I get the itch to come back home," the door's open," Hogan stated.
