Conor Sammon flashes a shot wide of the Celtic goal as Hearts make a determined start.

The hosts get the game going.

Hearts: Hamilton, Paterson, Souttar, Rossi, Rherras, Walker, Cowie, Djoum, Nicholson, Watt, Sammon. Subs: L.Smith, Oshaniwa, Buaben, Zanatta, Paton, Muirhead.

Celtic: Gordon; Lustig, Toure, O’Connell, Tierney; Forrest, McGregor, Brown, Armstrong; Griffiths, Dembele. Subs: Fasan, Izaguirre, Ciftci, Sinclair, Rogic, Johansen, Janko.

Hearts make three changes.  Out go Liam Smith, Alim Ozturk and Prince Buaben. In come John Souttar, Don Cowie and Tony Watt, the former Celtic striker making his Hearts league debut against his old club. 

Kolo Toure makes his first start for Celtic, striker Moussa Dembele is also in from the start, and new signing Scott Sinclair is on the bench.

We won't linger on that game, the first goalless draw of this fledgling Premiership season. It's on to Edinburgh we go now as champions Celtic prepare to open their campaign. 

An end-to-end flurry in the final minute, but like most of what preceded it, neither side can find any inspiration with the final pass.  In all honesty neither side really did enough to win it.  

Steven Anderson gets up well to head a flighted corner from the left back towards goal, but Dons keeper Joe Lewis collects it - and takes a whack for his troubles.   We're into two minutes of injury time now... 

Aberdeen's Ryan Jack almost obliges from a decent left-wing cross, but his well-directed header is saved by the diving Alan Mannus.

There's plenty of endeavour at McDiarmid Park, on a sunny day in Perth. Some of the challenges are getting a little spicy - Adam Rooney perhaps slightly fortunate to escape any punishment after colliding with Brian Easton.  But it would be a surprise if this game ended up anything other than goalless...

Former Aberdeen defender Willie Miller on Radio Scotland: "It's fierce, it's fiery and competitive.  I just wish someone would put their foot on the ball and produce a bit of quality."

A half-chance for Andrew Considine on the edge of the Saints box, but his left-footed drive over the turf does not have enough power to trouble Alan Mannus. Signs of life with 20 minutes left though... 

Saints boss Tommy Wright makes a second change, sending on midfielder David Wotherspoon for the ineffective Blair Alston. 

The highlights of this game might not take too long to edit, as things stand, but you can watch them on Sportscene tonight, at the new earlier time of 19:30 BST on BBC Two. Former Rangers striker Steven Thompson and ex-Hearts and Hibs midfielder Michael Stewart will join presenter Jonathan Sunderland to analyse all the action from this first weekend of the Premiership season.

Both teams make a change.  Aberdeen send on prolific striker Adam Rooney – who signed a four-year contract extension this week - for Miles Storey, while St Johnstone replace Graham Cummins with Chris Kane.

Well, 'claim' may be too strong a description for Kenny McLean after the Aberdeen midfielder goes down rather easily in the box.  Referee Willie Collum, who's got most things right today, waves it away.  Graeme Shinnie then sends a dangerous ball across the face of the box, but it doesn't find a taker.

Former Aberdeen defender Willie Miller on BBC Radio Scotland: "Someone needs to have a word in the ear of Wes Burns.  The Aberdeen centre-backs have come up all the way up for the free-kick and he whips it right across everyone and out for a goal-kick. But no-one seems to say anything these days. They just trot back and get into their defensive positions."  

Chance for Saints.  Good ball whipped across the face of goal from the right wing by Blair Alston, Danny Swanson directs it back into the box but Graham Cummins - under pressure from Anthony O'Connor - can't get any purchase on it with his left foot, and it rather dribbles into the grateful arms of Joe Lewis.

Some early team news from Tynecastle.  Scott Sinclair, who has completed a £4.5m move to Celtic from Aston Villa, goes straight into the squad for today's game. He is on the bench, while Kolo Toure makes his first start for the Hoops, and striker Moussa Dembele also starts.
