Sidelined / Suzanne Baltsar.

Enhanced descriptions from Syndetics:

From the author of the whip smart and charming Trouble Brewing comes a fast-paced story about a female football coach that will have you laughing out loud and cheering for the home team as you wait for the final whistle of the game.

When Connor McGuire loses out on his dream job of being the head coach of the local high school football team, he thinks life can't get any worse. Then he discovers just who got the coveted position--it was a handout to the kid of a well-known, successful college coach. Connor's sure this is just a publicity stunt, but the kid turns out to be not only a sharp strategist, but a driven and sexy young woman, too. Frustrated in more ways than one, Connor realizes that he might have to step up his game or risk losing altogether.

Coach Charlotte "Charlie" Gibb calls a flag on the play when she finds out that her very male, very attractive, but definitely-rooting-for-her-to-lose assistant coach resents her for taking what he considers to be his rightful position. But never one to back down from a little healthy competition, Charlie is determined to prove her worth--both on and off the field.

Baltsar's "sweet, funny, witty, addictive writing," ( New York Times bestselling author Samantha Young) is not to be missed!
