“Suits” (9 p.m., USA): “Suits” is finally back with some fresh episodes and, yes, that’s Olympic swim sensation Michael Phelps dropping by in a cameo role. Seems that Harvey (Gabriel Macht) and Dana (Abigail Spencer) are determined to sign the star athlete as a client.

“Sirens” (10 p.m., USA): “Scrubs” meets “Rescue Me” in the new sitcom “Sirens.” Produced by Denis Leary, it follows three emergency medical technicians who are aces when it comes to the job but can’t seem to get their personal lives together.
