Former Liverpool midfielder Lucas Leiva has been withdrawn from pre-season training with Gremio after routine scans revealed a possible heart problem.
The 35-year-old had met with his team-mates ahead of his first full campaign with the Brazilian side since returning on a free transfer from Lazio in the summer.
However, tests carried out by the club’s medical staff before these preparations began showed an “alteration of heart rhythm”.
As a result, Lucas has been removed from all physical training until further tests can be completed.
The former Brazilian international midfielder confirmed the news on Twitter on Tuesday.
In response to his tweet, Liverpool FC wrote: “We are all with you Lucas.”
And his former Lazio teammate Felipe Caicedo said: “Good recovery bro, you’ll come back stronger.”
