LOS ANGELES (thefutoncritic.com) -- FOX's "Prison Break" isn't ending anytime soon as the network has ordered a full season of 22 episodes of the freshman drama, a network source confirmed today.

The news comes as the series heads for a brief two-week hiatus following its October 3 airing.

It's not clear how FOX plans to roll out the back-nine order as it previously indicated "House" and season five of "24" would take over Monday nights beginning in January.

In any case, the current batch of 13 episodes is set to wrap at the end of the November sweeps period. It remains to be seen if the nine remaining installments will continue to run on Monday nights or turn up at some point next year as a fill-in for any potential schedule holes.

FOX is expected to provide additional details when it formally announces the news tomorrow.

Overall for its first four weeks, "Prison Break" has averaged a solid 9.028 million viewers according to final numbers released by Nielsen Media Research. More importantly, "Break" has nearly doubled the audience of its lead-in "Kitchen Confidential" for the past two weeks in both households and adults 18-49.

Paul Scheuring, Marty Adelstein, Dawn Parouse, Matt Olmstead and Brett Ratner are the executive producers of the series, which comes from Adelstein-Parouse Productions in association with 20th Century Fox Television.
