Stewart-Haas Racing has called a news conference Wednesday with driver and team co-owner Tony Stewart at 1 p.m. ET, the team announced Sunday night. Multiple sources confirmed to NASCAR.com that the driver will announce he is stepping away from NASCAR at the end of the 2016 season.

Stewart, a three-time champion and 48-time winner in NASCAR's premier series, currently ranks 25th in the Sprint Cup driver standings. He placed 11th Sunday at New Hampshire Motor Speedway, just missing his third top-10 finish of the season.
Stewart became a team owner through a partnership with Gene Haas starting in 2009; since then, the Stewart-Haas team has grown from a two-car to a four-car operation. Two of the team's drivers -- defending series champion Kevin Harvick and former series champ Kurt Busch -- qualified for this year's Chase for the NASCAR Sprint Cup playoffs.
