Kingsley was included in the Tigers’ starting line-up for the first time since September when replacing the injured Elder – who came off with a hamstring injury in the Boxing Day defeat against Nottingham Forest on Boxing Day – at the Kiyan Prince Foundation Stadium
However, the Scotsman was forced to hobble off the pitch himself with another hamstring problem before the break, joining a growing list of absentees ahead of the trip to Sheffield Wednesday on New Year’s Day.
“It looks like a hamstring injury for Stephen – I’m gutted for him,” said McCann.
“It didn’t look too good for him coming off. He was in tears a little bit. He’s not having much luck with injuries.
“This was an opportunity for him to get his place in the team with Callum doing his hamstring as well. It’s not ideal for him but we’ll rally around Stephen.
“With Callum we’re going to have to take it week by week,” he added. “I don’t think it’s too serious. It’s not going to be a two-month job but I’d say probably three to six weeks.
“We’re lucky in that we’ve got another very good left-back in Brandon Fleming while Eric Lichaj can play there as well, so we’re okay.”
