As previously announced, Katee Sackhoff isn't simply coming to 24 next season. Her character is bringing a secret past with her.

We can now expound on that past, as Clayne Crawford has been tapped to play a recurring role on season eight.

Reports state that Crawford - who has several episodes of Jericho - will play a "bad boy" that has history with Sackhoff's CTU analyst.

The eighth season began production last month, as Crawford is the latest of several additions to the 24 cast, including Mykelti Williamson, Freddie Prinze Jr., Doug Hutchinson, Jennifer Westfeldt and Anil Kapoor.
