Carl Edwards is expected to announce Wednesday that he plans to retire immediately from NASCAR racing after a 13-year career in the Cup Series where he won 28 times in 445 starts, according to sources.
No immediate reason was available why the 37-year-old Edwards would retire nor who would replace him at Joe Gibbs Racing.
JGR driver Daniel Suarez, who shares sponsor Arris with Edwards and was set to defend his Xfinity Series title in 2017, is a possible replacement.
