Inverness were held 2-2 by the Scottish Championship’s bottom club Alloa after a dramatic second half.
Caley Thistle manager John Robertson was on compassionate leave after a family bereavement, with Neil McCann announced after the game as interim manager in his absence.
Nikolay Todorov twice went close and Roddy MacGregor had a goal disallowed as Caley Thistle failed to make inroads before half-time.
Alan Trouten wasted a chance to double Alloa’s lead and it looked costly as Inverness hit back with two goals in as many minutes.
Keatings’ fellow substitute Miles Storey, though, saw a penalty saved by Parry and then had a goal disallowed before Trouten atoned for his earlier miss by equalising with an 87th-minute penalty for Alloa.
