Liverpool manager Jurgen Klopp has claimed that James Milner should be back in full training by early August.
The Reds vice-captain has been struggling with a quad injury since their Premier League Asia Trophy victory over Leicester City in Hong Kong on Saturday.
Liverpool are currently in Germany ahead of clashes with Hertha Berlin and Bayern Munich, but Milner is unlikely to feature in either game.
"It was clear from the first day there's a little bit of tendon involved, so that means that it's around 10 days," Klopp told the official Reds website.
"That means he will do his rehab here in Germany and then should be fit again when we're at home."
Liverpool begin their Premier League campaign with a trip to Watford on Saturday, August 12.
