Zverev confident of retaining Olympic gold despite injury concerns
Zverev slipped during his third-round triumph against Cameron Norrie in SW19, bowing out of the competition in a five-set to Taylor Fritz in the following round.
The world number four has since competed in the Hamburg Open, a title he won a year ago, but fell at the final hurdle to Arthur Fils in a decisive final set tie-break.
Zverev, who became the first German to win an Olympic gold medal in singles since Steffi Graf did so in 1988, beat Karen Khachanov in the final in Tokyo four years ago.
The German described his injury as a bone edema and torn capsule and said that it did not require surgery ahead of the games.
"To be honest, you know, the risk will stay for the next two, three, four weeks maybe because that's how long the bone heals, and that's what everybody told me," Zverev said.
"But, at the end of the day I also knew that I don't want to rest for four weeks because, now we're playing on the surface where I don't see that big of a risk of doing the same motion again and doing the same movement again."
The tennis will take place at Roland Garros, a venue well-known to Zverev who reached the French Open final earlier this year, losing out on a first grand slam title to Carlos Alcaraz in five sets.
Zverev is also on the shortlist of German athletes who could be flagbearer for the nation during Friday's opening ceremony.
"If someone told me that I should walk in as a flag bearer, it would mean even more to me, to be honest (than winning the Olympics)," Zverev was quoted by SpilXperten.
"Leading an entire nation and so many top German athletes into the Olympics is simply the greatest honour an athlete can receive.
"And of course, the gold medal I won at the last Olympics is one of the highest achievements you can have in sports and for me personally the greatest success in my career."
