Words are rive that Bryan Fuller has ditched "Heroes" for the second time. The producer/writer initially walked out of the series in 2007 to concentrate on his new show "Pushing Daisies" but he was back a year later after "Daisies" got canceled by ABC, signing a two-year deal with Universal Media Studios to be the writer starting episode 3.20.

This time around, he is out from the show to pursue a project with NBC and not because he has a creative difference with creator Tim Kring like some have reported. "I'm crafting two pilots right now and it's a lot of work," Fuller told EW. "It was just too hard to [juggle] Heroes and my development; something had to give."

Fuller is credited as one of the writers who wrote the series' best episodes in the first season such as "Company Man" and "Collision". His return at the end of 2008 was thought to help the show's less successful second and third season.

In a separate statement to Ain't It Cool News, Fuller explained his departure in more details. He said, "Development was really starting to heat up, And it appears like I may be writing multiple pilots for NBC so that wasn't leaving a ton of room for 'Heroes,' unfortunately. We crafted some really great arcs for the season that I'm excited to see come to fruition. I love that cast dearly and am sad to go, but the plate - she was over-flowing."

"Heroes" will be back with the fourth volume in Fall.
