Glentoran missed out on the chance to open up a six-point lead at the top of the Irish Premiership table after playing out an enthralling 1-1 draw with rivals Linfield at the Oval.
Declan Devine's side went ahead on 21 minutes as Pat Hoban kept his cool from the penalty spot following Kirk Millar's foul on James Singleton.
Linfield responded on 62 minutes, also from the spot, as Chris Shields fired home after Marcus Kane brought down Matthew Fitzpatrick.
Both sides maintain their respective unbeaten starts to the season, with the Blues holding three games in hand over the Glens.
Linfield made a bright start to the game and in the first minute, as Kieran Offord forced Alex Mills into a low save.
Four minutes later, Fitzpatrick had his head in his hands as he swept wide after being gifted possession by a wayward back pass from Kane.
The momentum of the game shifted on 20 minutes as referee Ben McMaster awarded a penalty as he deemed Millar clipped Singleton.
Hoban stepped up and sent Chris Johns the wrong way to open the scoring against the run of play.
The Blues were handed a route back into the game just after the hour mark as Kane dragged down Fitzpatrick, with McMaster pointing to the spot after consulting with the linesman.
Shields stepped up and fired home to level, but it was end-to-end for the remainder of the game with both sides forced to settle for a point.
That was despite Sean Brown smashing the crossbar for the Blues and Jordan Jenkins firing over for the Glens in injury-time.
