NCIS: Los Angeles and Three Rivers Recast Key Roles

A pair of new fall shows have undergone casting changes already.

First, former CSI star Louise Lombard will NOT be making the trek to NCIS: Los Angeles, even though she appeared in the two NCIS episodes that served as a backdoor pilot for the spin-off.

Instead, the series will recast its female lead, who will have the good fortune of starring alongside LL Cool J and Chris O'Donnell.

Similarly, The Hollywood Reporter, states that Three Rivers is searching for a new head of transplant surgery, following the decision to replace Julia Ormond. It shouldn't be too hard to find a woman to work opposite star Alex O'Loughlin (pictured).
