The Hoops won 3-0 in Perth courtesy of first-half goals from Olivier Ntcham, James Forrest and Leigh Griffiths, with Johnston coming on as a substitute midway through the second-half.
Johnston went down clutching his knee not too long after taking to the McDiarmid Park pitch and was actually asked if he wanted to be subbed back off again by Lennon.
However, the 20-year-old attempted to continue and Lennon revealed this afternoon that his decision to do so might have made matters worse:
Speaking via Clyde 1, Lennon explained: “It will be long term. It was a bad twist. He says there was contact but it doesn’t look like there was contact.
“It looks like he has twisted the knee and there is a bit of swelling there and ligament damage.
“It [playing on] might have compounded the problem.
“It was annoying for me because we were making a substitution and he said he was alright to carry on.
“But quite clearly after a couple of minutes that wasn’t the case. We had already made the substitution. So it was a learning experience.”
As was caught on camera during the game, Lennon appeared to be pretty annoyed with Johnston at the time, but does the severity of the injury now put a different perspective on things?
What do you think of the situation?
