Sturridge missed Thursday night's win over Bordeaux with a foot complaint after recently being sidelined with a knee problem.
Sturridge pulled out of Thursday night's Europa League squad ahead of the win against Bordeaux with a foot complaint, after recently recovering from a knee injury.
The forward has only made three appearances so far this season and is yet to feature under Jurgen Klopp. Sturridge had an injury nightmare last season, and underwent hip surgery in the summer which caused him to miss the start of the season, before picking up a knee injury with a collision with Jordon Ibe in training.
Molby wrote in his Liverpool Echo column: "It'll be an absolute nightmare for him to be on the sidelines again.
"He'll have worked so hard to get back after being out injured, and the blow will be felt just as much mentally as physically.
"Sturridge obviously has a problem. And while it's cruel to say he's not built for the game, there's more and more evidence pointing to the fact it's going to be difficult for him to ever play regular football at the top level."
There is no doubting the quality of Sturridge when he is fit. He is a striker that is capable of scoring in excess of 20 goals across the course of a league season, but his injury record is absolutely wretched and leads to questions from some fans as to whether he is worth all of the bother.
Liverpool fans must be hoping there must be one prolonged spell in the side not too far away, and hope that the scan on his foot injury reveals good news and that Sturridge was just being overly cautious when it came to feeling a slight niggle.
After all, there is no way he intends on getting injured. One can only hope he gets himself fit and gets people talking about his goals rather than different parts of his body in the future.
