“Necessary Roughness” (9 p.m., USA) wraps up its second season with a series of personal and professional crises. A casual observer of this melodrama, about sports therapist Dani Santino (Callie Thorne) and the athletes and teams that employ her, would have to remark how much the show has shifted the attention away from therapy — and even Dani — toward more colorful characters and situations.

Tonight’s episode continues television’s recent fixation with group therapy. After a drug binge culminates in a near-disastrous car accident, football superstar Terrence “TK” King (Mehcad Brooks) is suspended from the Hawks and sent to a posh rehab center. There he encounters a slick music producer played with gusto by Michael Imperioli (“The Sopranos”). He’s now on his seventh or eighth stint at rehab and knows how to work the angles — knowledge he imparts to the arrogant wide receiver. This is a great role for Imperioli, and fans who miss Christopher Moltisanti should not miss it.

Meanwhile, TK’s departure spells major trouble for his team on and off the field, a crisis compounded by at least two missing persons cases and a sports gambling disaster that hits close to home.

• Meanwhile, on “Royal Pains” (8 p.m.), USA’s other popular series, a visiting pop star seeks treatment for “exhaustion,” but shows symptoms of a more urgent nature.

• Coverage of the Republican National Convention (6 p.m., CNN, Current; 7 p.m., PBS, Fox News, MSNBC; 8 p.m., Bloomberg; and 9 p.m., ABC, CBS and NBC) continues.
