Milos Raonic will replace Felix Auger-Aliassime on the Canadian team at the Davis Cup Final 8 next month.

Tennis Canada says Auger-Aliassime, from Montreal, plans to recover from the season and devote time to his humanitarian work in Togo.

Canada will play Germany in the quarterfinals of the Nov. 19-24 competition in Malaga, Spain. Raonic, from Thornhill, Ont., joins a roster that includes Denis Shapovalov of Richmond Hill, Ont., Montreal's Gabriel Diallo, Alexis Galarneau of Laval, Que., and Vasek Pospisil of Vernon, B.C.

At No. 22, Auger-Aliassime is the top-ranked Canadian player on the ATP Tour. Raonic, a former world No. 3, is currently ranked 244th after an injury-plagued season.

In a news release, Auger-Aliassime says it was a tough decision to miss the competition but adds it's "hugely important" for him and his family to give back to others.

Auger-Aliassime was recognized for his philanthropic work in West Africa when he received the ATP's Arthur Ashe Humanitarian Award last year.
