There have been rumors about Spong for weeks now, with the former K-1 Heavyweight being a hot commodity on the open market. It appeared that Spong was linked to K-1 for a while, as he was used in the promotional materials for the K-1 Open Tryouts in Los Angeles, but those close to him in the Netherlands were saying the opposite; that he was unhappy with K-1 and didn't trust them. In a press release yesterday (sorry, we've been down for 24 hours), Glory announced that Tyrone Spong had signed with them and will be a participant in their tournament in December in Japan.
Spong makes a welcome addition to the Glory World Series tournament in what could be one of his last active years as a Kickboxer, as he resides in Florida, training with the Blackzilians team (also known as Team Jaco) and is managed by Authentic Sports Management. Spong is essentially surrounded by MMA and talk of him making a MMA debut at some point in the near future has not died down at all. Whatever his decisions for signing with Glory over K-1 are, they are his own and he has not publicly explained it, but his reasons are his reasons.
