Dark Blue
10/9c TNT
Executive producer Jerry Bruckheimer's gritty cop series about a deep undercover unit continues its freshman season. In this episode, team leader Carter Shaw — he of the street-smart focus, hard-bitten worldview and obligatory facial stubble — lurks deep in the shadows, consulting his dark underworld acquaintances to take down a crooked yet decorated cop. But this assignment to crush a fellow police officer tests Ty's moral code — particularly after his wife floors him with big news. Michael Biehn, who played Kyle Reese in 1984's The Terminator, guest stars. — Dean Maurer

America's Got Talent
9/8c NBC
The ratings-grabbing summer talent contest begins morphing its way to the next phase — the semifinals, which kick off next Tuesday. But first we have tonight's results show. Last night the final 10 acts from the Top 40 took the stage, and with nerves fraying they now await their entertainment fate. Five acts are slated to be eliminated while five winners jubilantly advance to the Top 20 and the semifinals, their hopes for the $1 million prize still alive and well. — Dean Maurer

Crash Course
9:02/8:02c ABC
ABC makes a dent (literally) in the reality genre with this new revved-up vehicle, in which five two-member teams of significant others compete in extreme driving-course challenges, such as "car bowling," reverse drag racing (complete with a towed boat) and parallel parking (but while driving a lumbering behemoth, like a tank or a bus). The fast-and-furious entrants gearing up for competition in the premiere include fashion-model single moms, a husband-and-wife team, siblings from Michigan and competitive best buds. Orlando Jones and Dan Cortese are the hosts. — Dean Maurer

The Kennedy Brothers: A Hardball Documentary
9/8c MSNBC
"Join us... to stand for progress... to go forward until the United States achieves that great goal of practicing what it preaches." From a lofty Barack Obama speech? Nope. Try John F. Kennedy circa 1960. Reported by Chris Matthews, this look at the lives and legacies of Kennedy brothers Jack, Bobby and Ted — who each, in his own way, shaped America, its culture and politics — features archival clips, including Ted's stirring eulogy of Robert, and interviews with Kennedy insiders and scholars. — Jeff Gemmill

Hard Knocks: Training Camp with the Cincinnati Bengals
10/9c HBO
It's not all hard knocks at the Bengals' preseason facility in Georgetown, Ky. The team's preparations for its second exhibition game with the Patriots are interspersed with a training camp visit by Muhammad Ali, and the traditional camp "talent" show put on by Bengal rookies. — Dave Roeder
