Thiago has been praised for how he has got to grips with the Premier League so far this season, but picked up an injury in Liverpool’s 3-0 win over Crystal Palace on Saturday.
The midfielder suffered a calf issue during the Premier League clash and the club are waiting for the results of his scan to determine the severity of the niggle.
The Reds though have seen enough to know Thiago will miss their EFL Cup tie against Norwich City and Premier League meeting with Brentford next weekend.
“Thiago, how the gaffer said after the game, it was a calf injury”, Lijnders told the club’s official site.
“I can’t say now how long it will take but definitely not tomorrow and not at the weekend.
“Let’s get the scan results back and we have a proper diagnosis.
“A shame as well because he was taking the game by the hand, he was a proper playmaker in my opinion. A shame that we miss him.”
Liverpool have enjoyed a positive start to the new Premier League season, picking up 13 points from their opening five league games.
They will hope Thiago is back at Jurgen Klopp’s disposal soon.
