Celtic midfielder David Turnbull admits he and his team-mates didn't do well enough to "dig out" a result against Livingston.
The Premiership champions could only draw with David Martindale's side as they handed Rangers the chance to go 23 points clear at the summit.
It was a makeshift line-up with 13 players and manager Neil Lennon in isolation after being identified as close contacts of Covid-positive Christopher Jullien.
Turnbull said: "It was a tough one to take. It wasn't a good game but we have to dig these results out. We didn't do that, which was sad.
"We are missing bodies and it's tough but we just need to get on with it. We need to keep fighting for everybody.
"Livi came and played the way they always do but we need to handle it better.
"It's been a weird time for everyone with the gaffer and John not here, and all the boys.
"It's also tough not having any strikers available and it's meant playing boys who haven't played there before.
"We had wingers up there against Hibs and then Tom as a striker against Livingston.
"That was always going to be tough but we have to cope with it better."
