The 26-year-old's debut season for Liverpool has taken another disappointing twist, according to The Sun.
Isak is set to miss his side’s clash with Manchester United after picking up a groin injury during a training session this week.
He will now undergo an exam to understand the severity of the issue and determine whether the £130 million man will feature again this season.
Isak has managed to score just four goals in 21 games across all competitions for Liverpool since his move from Newcastle.
Injuries have certainly played a role in Isak’s struggles, including a broken leg that sidelined him for several months earlier in the year.
