Instead of running repeat episodes of "Invasion" on two Wednesdays in December, ABC is moving "Alias" from Thursdays at 8 to follow "Lost," according to Zap 2 it.

On Dec. 7 and 14, new episodes of "Alias" will air at 10 p.m. What will replace "Alias" on Thursday nights is not yet known.

ABC's attempt to gain a foothold on Thursday night hasn't fared well this year. After respectable ratings early the season, "Alias" has seen a decline each week. The show that followed it, an updated "Night Stalker," has already been cancelled after only six episodes.

The episode of "Lost" that will air on Dec. 7 will be a rerun. There has been no announcement if there will be a new episode or a rerun of that show on Dec. 14.

"Invasion" is presently expected to return to its previous time slot in late December unless "Alias" can deliver stronger ratings for the network.
