Former world No. 1 Andy Murray suffered a quad tear and that forced him to skip the Tokyo Olympics singles event. Just before the start of the tennis event at the Tokyo Olympics, Murray pulled out of the singles event but decided to play doubles.
"I have never had any muscle injuries in my career, so I didn't really know what they felt like. It was a difficult one," Murray said, per Sky Sports. "It was hard and frustrating again to have to miss another big event.
Granted, I got the opportunity in doubles and we were close to getting into the medal rounds. "We were potentially going to go to Canada, but just felt like maybe needed to have a few more days of rehab to make sure the quad was really fine and recovered before starting to play again.
"Here, I feel good again, but as I said earlier in the year, I can't say with any great certainty that I'm going to be feeling good for three, four months in a row."
Murray focused on short-term goals
Murray is currently focused on the Cincinnati Masters and US Open.
"I think I need to set short-term goals because it's been very difficult to plan sort of medium and longer-term targets, because of just various different issues that I have had this year," said Murray. "I just try to focus on the short term.
"I can't really look too far ahead right now. I think like my team planning like my physical conditioning and my scheduling and everything, I think that can be their job to sort of plan those things out, but for me I just need to kind of like take things very much like each week at a time just now and give all my energy to each match and each event that I play and see where I'm at at the end of the US Open."
Murray, now ranked at No. 105 in the world, received a wild card into Cincinnati. "It was nice obviously to get in directly," he said. "Obviously that would be my goal to try and be getting into all of these tournaments by right.
"If I think physically I'm in good health and the tournaments want to give me the opportunity and I'm still winning matches at this level, then I don't have a problem taking the wildcards. "Ultimately I would want to get into these tournaments on right, and that's why I want to be fit and healthy for a number of months in a row to give myself the opportunity to do that."
