Lee Burge

Enlarged heart following covid in early January, vaccinated, out of action because of heart condition, Jan, 2022, UK

It sounds like the club boss Lee Johnson suspects the shots over covid:

"Johnson said last week that Burge was undergoing tests on a heart complaint, and today he went into more detail saying the 29-year-old faces several more weeks out of action although he is expected to make a full recovery.

"He has still got an issue," he said of Burge,

"It's effectively a slightly inflamed heart and it seems to happen a lot after these injections, or potentially Covid - I'm not sure which.

"The weighting would be on Covid, but you can't rule out the vaccination."
