Quote MessageWe had good spirit and good energy. We had a young, inexperienced team and they fought together very well. There are lots of positives to be taken from the game."
Ronny Deila, Celtic manager
We will have highlights of yesterday's Premiership games online from 18:00 GMT, with a Liam Boyce hat-trick and an Aberdeen comeback for you to see.
The action from Tynecastle can be seen on Sportscene at 22:00 tonight on BBC Two Scotland and online from midnight.
Celtic were without top scorer Leigh Griffiths, captain Scott Brown, playmaker Kris Commons and the experienced Charlie Mulgrew today. They then lost Stuart Armstrong and Dedryk Boyata to first-half injuries. Will Ronny Deila aim to strengthen his squad next month?
We'll hear from Ronny Deila soon, I'm sure. How will the Celtic boss be feeling after conceding such a late goal? The visitors looked to have taken control after Tom Rogic made it 2-1.
Celtic bossed the early stages and were again on top after a really scrappy opening to the second half but Hearts showed great spirit to fight back twice.
Robbie Neilson is sounding very hoarse in his BBC Radio Scotland interview, sticking to his "our aim is top six" mantra but he lets it slip for a second, saying Hearts will try to chase down Aberdeen in second place.
Quote MessageIt shows the distance that we've come that the players are disappointed to only get a point against Celtic."
Robbie Neilson, Hearts head coach
Here's a look at that Osman Sow thunderbolt that levelled the game right at the end. The big Swede had a very quiet game, saving his best for a spectacular late cameo.
On second viewing, it looks like there might have been a wee deflection on the shot.
Well, that was absolutely exhausting and I was just watching and making typing errors... The game was played at a real hammer and tongs tempo, with lots of bone-shuddering tackles and the teams served up four very good goals.
Celtic move one point clear at the top of the Premiership pile and third-placed Hearts edge one point nearer Aberdeen.
Chris McLaughlin
BBC Sport Scotland at Tynecastle
"What a real feast of festive football here at Tynecastle. Great goals, tasty tackles and tireless passion from both sets of players. The points are shared but Hearts' late equaliser felt like a winner for the home side. Robbie Neilson ends his victory drought but it's disappointment yet again for Ronny Deila. Cracking entertainment in the capital."
We're halfway into four minutes of stoppage time and Hearts are chasing a winner, with Celtic now rattled.
Billy King is brought down 30 yards from goal. The free-kick is rolled short to Osman Sow and the big Swede absolutely hammers a strike into the top corner. Craig Gordon could only stand and watch as the ball zipped past him.
Billy King, sporting the short-sleeves and gloves combo, does well to drive into the Celtic penalty box but then fluffs his lines with an appalling shot.
We're into the last five minutes as Hearts throw on teenager Dario Zanatta for Morgaro Gomis. Can the Canadian kid make himself a hero?
