Each show is to start off with a 90-minute premiere followed by 11 one-hour episodes.
The announcement was made Wednesday by Jeff Wachtel, USA's president of original programming and co-head of original content for Universal Cable Productions.
"A Legal Mind" stars Patrick J. Adams, Gabriel Macht, Meghan Markle, Gina Torres and Rick Hoffman.
The cast of the football-themed drama "Necessary Roughness" includes Callie Thorne, Marc Blucas, Mehcad Brooks and Scott Cohen.
"At USA, we like to say that the quality of the material advances the projects -- and these are two great pilots!" Wachtel said in a statement. "'A Legal Mind' and 'Necessary Roughness' take our original series to a new level, while honoring the character-brand filter that has been so crucial to our success."
The network did not say when the shows are expected to debut.
