A big part of being a doctor is not losing your patient. That's just one of those lessons that they teach you in medical school. Unfortunately, it's a lesson that is forgotten on 'Miami Medical' (Fri., 10PM ET on CBS). Two doctors return to a room, only to find that their patient... has disappeared.

On the latest episode of 'Miami Medical' (Fri., 10PM ET on CBS), the head doctor encounters an unexpected patient. A giant truck pulls up to the hospital, and Dr. Proctor (Jeremy Northam) wants to know what the hell is going on. What's up with the huge truck? Does the new patient weigh 800 pounds?

(S01E01) Like CBS's other medical drama for this TV season, 'Three Rivers,' 'Miami Medical' is very earnest and filled with moments that strive for poignancy. The fact that it doesn't succeed is less a reflection on the network than the creators. At least CBS gets credit for realizing that 'Miami Medical' was less that the sum of its aspirations and planted it in the little viewed Friday, 10 PM time slot.

"It's 'M*A*S*H' in paradise," exclaims a character in the new CBS drama 'Miami Medical.' And that's precisely the show's core premise, according to executive producer Jeffrey Lieber.

'Miami Medical' (premiering Fri., April 2 at 10PM ET) stars Jeremy Northam as mysterious, war-tested Dr. Matthew Procter, who joins a high-adrenaline trauma team that treats life-threatening injuries.

Lieber spoke to AOL TV about his inspiration for 'Miami Medical,' fitting into the hospital drama landscape and how he feels about the end of the show he co-created, 'Lost.'

Good news for Patrick Warburton fans; disappointing news for Jenna Elfman fans. And if you have a deep affection for Jeremy Northam, this should make you happy, too. Confused? Don't be. I'm just laying out the essence of the CBS midseason juggle.

On Mondays, beginning February 1, Accidentally on Purpose will be shelved... but only for a few weeks. Taking the 8:30 Monday slot will be the return of Patrick Warburton, the best thing in Rules of Engagement.

That's not all. On March 31, the 8:30 slot in which Gary Unmarried airs, will be assumed by Accidentally. That's not because Gary's being canceled; it will have completed its season order by then.

CBS announced a mid-season schedule Thursday, which was highlighted by the introduction of Jerry Bruckheimer hospital drama 'Miami Medical' and the return of David Spade comedy 'Rules of Engagement.'
