Leigh Griffiths scored against former club and boyhood heroes Hibernian for the first time to give Celtic a narrow 1-0 Premiership win at Parkhead.
In Brendan Rodgers' 100th game as Hoops boss, Griffiths struck in the 27th minute before an injury minutes later saw him replaced by Moussa Dembele.
The Scotland striker's 14th goal of the season was enough to take all three points from a Hibs side who had drawn 2-2 with Celtic in their previous two league games this season.
He had recovered from an ankle knock to come off the bench and score the winner at Partick Thistle on Tuesday and there was no surprise that he replaced Odsonne Edouard, while stopper Jozo Simunovic came in for Mikael Lustig with centre-back Dedryck Boyata moving to right back.
Striker Oli Shaw replaced Simon Murray for the visitors who looked far from overawed in the early stages.
However, Celtic should have taken the lead in the 14th minute after midfielder Callum McGregor was fouled by Dylan McGeouch just outside the box.
Griffiths' curling free-kick was parried by Ofir Marciano and, with the goal gaping, Scott Sinclair somehow managed to hit the post.
The match opened up further and Griffiths volleyed wide from a Sinclair cut-back.
At the other end, Celtic keeper Craig Gordon used his foot to block a Brandon Barker drive after the attacker had outstripped the Hoops defence.
Hibs had themselves to blame for Griffiths' goal. Skipper Paul Hanlon failed to deal properly with a Kieran Tierney cross from the left, his weak headed clearance immediately returned on the angle past Marciano by the striker.
There was a muted celebration from Griffiths in front of the travelling fans, and minutes later he limped off.
Dembele came on for his first piece of action this year, with Rodgers having recently expressed concern that transfer speculation had affected him, and ended the afternoon with a booking for simulation.
In the 51st minute Sinclair had another good chance but Marciano saved, while Hibs midfielder John McGinn forced a decent save from De Vries with a powerful 25-yard drive in the 78th minute.
Celtic stood firm although, with a Europa League tie against Zenit St Petersburg coming up, they will wait nervously on news of the damage from Griffiths' injury.
