The England international could now be out for at least six weeks, adding to Leicester's injury problems this term.
"I just spoke to the doctor. That'll be a huge blow for us," said Rodgers.
Speaking to BBC Radio Leicester, Rodgers added: "It's not good news. He needs an operation. He'll be out for a minimum of six weeks. Part of the bone in his knee has come off, so he'll need it repaired.
"He's had niggles with it. We tried to recover him on Thursday but it's a bad one for him.
"It's been irritable and today it's made it worse. The consolation is it's not as long as it looked like. I'll know more on Monday."
Bringing Barnes on in a game that you’re chasing against a championship level Watford team in Europe would be considered as tactically inept as you get.This crazy workload is wrecking young footballers, Call Klopp all the names under the sun but he's correct
"Of course, Jonny has had a calf issue for a period of time. We’re managing that, but he felt it too much today, so we’ll have to wait 24 hours on that I think."
So playing him from the start would have been tactical genius thenBringing Barnes on in a game that you’re chasing against a championship level Watford team in Europe would be considered as tactically inept as you get.
Todays tactic of not pressing until you go a goal behind was another master class. Brendan didn’t do himself any favours!
Such a shame NFP went to Bristol City. Were crying out for a manager of his calibre.Bringing Barnes on in a game that you’re chasing against a championship level Watford team in Europe would be considered as tactically inept as you get.
