Dominic Monaghan will be part of the new ABC series "Flash Forward," IGN.com reports, citing unnamed sources.

Speculation that Monaghan might be returning to ABC first began when an "ABC House" promo featuring the former "Lost" actor surfaced.

"There is a lot of speculation out there right now, but we’re not confirming any casting at this point," an ABC spokesperson told the Web site.
