MMAjunkie.com today confirmed that while the matchup is far from official, it’s in the works for a headlining spot at the event.

Although not officially announced, UFC 118 is expected to take place Aug. 28 at the TD Garden in Boston. Two high-profile lightweight fights are currently on tap for the Northeast event: newly minted champion Frankie Edgar fights the man he deposed for the belt, B.J. Penn, in an immediate rematch of their recent UFC 112 bout, and two-time contender Kenny Florian faces standout Gray Maynard.

The weight limit of Couture vs. Toney is currently undetermined. Couture is now two fights into a second stint as a light heavyweight, while Toney is primarily regarded as a heavyweight in the boxing world.
