According to TV Guide Magazine, Jackson was “exhausted… from months of harrowing storylines” which included but were certainly not limited to the deaths of Lucky’s son and wife, as well as the character’s relapse into the world of prescription drugs.
Making an abrupt exit apparently was not the suds vet’s first choice. Per TV Guide Magazine, Jackson is said to have reached out to GH‘s Powers That Be about lightening his load, to no avail. He also unsuccessfully attempted to rekindle Lucky’s fan-favorite romance with Rebecca Herbst’s Elizabeth.
Jackson is slated to make his final GH appearance sometime between mid-December and early January 2012. According to Soap Opera Digest, which first reported on his exit, there is no word yet on any plans to recast the role of Lucky, which was played by two others — Jacob Young and Greg Vaughn — in between Jackson’s original 1993-99 run and his current encore, which began in late 2009.
