Black Cats boss Steve Bruce says he has taken no decision on the future of Gordon - as Celtic weigh up a cut-price move for the Scotland stopper.
He said: “I’m going to swim with the goalkeepers until we get back and then we’ll see where we are up to with Craig. We’re back on July 6, so we’ve got nearly seven weeks once we’ve come back to see where he is and where his rehabilitation has taken him and if he’s going to be a long term casualty.
“But I’m not going to do anything just yet. Remember we’ve also got back-up in Trevor Carson – he is a confident goalkeeper.”
