Before Murray versus Isner, the host country's other central member,
guarding US Open hero Emma Raducanu, was beaten 6-3, 6-3 via Caroline Garcia of France.
When inquired as to whether he intends to return in 12 months' time, 35-year-old Murray answered:
"It really relies on how I am truly. All things considered, we'll attempt to continue to play.
In any case, the issues I've had with my body over the course of the years are very hard to anticipate."
Murray required various procedure on his hip and presently has a fake joint.
He likewise as of late confronted a stomach issue which hampered his arrangements last week.
As well as turning into Britain's first men's singles title victor in quite a while at Wimbledon,
when he guaranteed the prize in 2013 - and adding one more in 2016
Murray has consistently figured out how to make essentially the third round in his 13 earlier appearances.
