The Brazilian defensive midfielder limped off after just four minutes in Liverpool’s game against Manchester City on Sunday.
Lucas picked up the thigh injury during Liverpool’s pre-game warm-up against Manchester City, but started the game regardless, lasting just four minutes before being replaced by Jonjo Shelvey.

The injury is a huge blow for Lucas, who only recently returned from a cruciate ligament injury that caused him to miss the second half of last season.
“[It] looks like Lucas will be out for a few months. Early indication is he will be back after 2-3 months out,” Brendan Rodgers told reporters at a press conference ahead of Liverpool’s Europa League second leg tie with Hearts.
Rodgers is, however, optimistic that Lucas can make a quick recovery from the injury, adding: “He is a quick healer so I expect him to be back sooner than that.”
Lucas will miss a number of important fixtures for Liverpool, including a visit from Manchester United and the Merseyside derby.
The Brazilian took to Twitter to reveal his disappointment at picking up another serious injury.
He wrote: “No words to describe my feelings at the moment. It is been hard to be positive but I am sure better days will come. YNWA.”
