Jürgen Klopp has eased fears of Alberto Moreno suffering any serious injury after Liverpool's 2-1 loss to AS Roma to sign off their tour of the United States in St. Louis on Tuesday.
The left-back had to be substituted with nine minutes remaining after picking up a knock, with Connor Randall coming on in his place as the Reds slipped to defeat at the Busch Stadium.
With James Milner, who played the first-half on the left side of defence, the only current back-up option to Moreno - any severe problem would surely have left the Reds short on options for their Premier League opening weekend clash with Arsenal.
But Klopp, speaking to reporters at his post-match press conference, insisted that the knock was serious as he explained: "Yes, [he is ok], it was a dead leg in the hamstring. That's all it is. He couldn't activate the muscle so you cannot play. That's how it is."
Although Moreno's standing among supporters remains mixed at best - due to his erratic performances - the news should come as a positive given the lack of left-back depth.
Particularly, with Klopp's injury list already featuring a number of names who would have been expected to start away at Arsenal on August 14, the Reds can ill-afford too many more absentees.
Klopp confident Moreno hasn't suffered significant problem
Loris Karius' broken hand, suffered in defeat to Chelsea last week, saw him join defenders Joel Matip, Mamadou Sakho and Joe Gomez out.
Midfielders Lucas Leiva and Ovie Ejaria will both miss the start of the season with muscle injuries, while Divock Origi was left out of the 24-man squad to face Roma due to a groin injury that is thought to be minor.
The extent of the damage has yet to be revealed, with the 21-year-old having marked his return to the first-team with an excellent goal against AC Milan at the weekend.
Klopp will hope to have Matip and Origi back in training within the next few days as the Reds return to the UK to prepare for final friendlies against Barcelona and Mainz.
Meanwhile, there has been no update on Liverpool's pursuit of a left-back to compete with Moreno. Brad Smith's £6 million sale to Bournemouth last month leaves no natural left-back deputy, with the versatile Gomez out with an Achilles problem and Jon Flanagan expected to go out on a season-long loan to Burnley.
And with Ben Chilwell, whom Liverpool had watched since before Christmas, having penned a new five-year deal with Leicester City - Klopp has yet to identify any leading candidates and looks set to instead use Milner as a second-choice.
Though the German could yet change his mind and look to sign a new left-back, he has insisted he will not be forced to pay over the odds - having had a £7 million bid for Chilwell rejected as the Foxes sought as much as £10 million for a teenager yet to make his league debut.
