BEAVERTON, Ore. (AP) — Nike has extended its sponsorship deal with the National Women's Soccer League through 2019.

The Beaverton, Oregon-based shoe and apparel company has outfitted the women's professional league with uniforms and training gear for each of its teams since it launched in 2013.

The announcement Wednesday comes as the NWSL prepares for its championship game Thursday night between the Seattle Reign and FC Kansas City at Providence Park in Portland, Oregon. Both teams worked out at Nike's headquarters Tuesday.

The sponsorship deal has been key for the NWSL. No other professional women's soccer league in the United States has lasted more than three seasons.

Nike will also supply the league's official game ball.
