According to Yahoo blog Eh Game, Eugenie Bouchard and coach Thomas Hogstedt have parted ways after only six months.
Hogstedt has already signed on to coach American Madison Keys.
Ex-coach Nick Saviano appears to be back in the Bouchard mix, though nothing has been made official.
Saviano was the 22-year-old's coach for eight years when she broke into the top 10 in 2014. Bouchard reached the semifinals in three of the four majors that year before the two parted ways acrimoniously at season's end.
Bouchard then struggled last season, falling to 48th in the world before suffering a concussion as a result of a fall at the U.S. Open.
She currently sits 46th in the world rankings.
