With two minutes to go and nothing between the two teams, a try from Canadian scrum-half Morgan Williams looked to have won the game for Saracens – former Leicester fly-half Andy Goode having added the extras.
But with the final whistle imminent, young Leicester flanker Will Skinner broke the hearts of the home fans by crossing the line for the visitors to take them to within two points.
And when fullback Tim Stimpson held his nerve and struck the conversion, that meant that there was no daylight between the sides – Saracens having been coached by former Leicester centre Rod Kafer following the off-season dismissal of Wayne Shelford.
Earlier, the boot of Goode had fired Saracens into a 6-3 lead on the 40-minute mark with two penalties to one, but Stimpson quickly beat that by nailing a further two, while Goode's third effort on 50 minutes tied the scores at 9-9.
With scoring at a premium, a fourth penalty for both Stimpson and Goode looked to have been the last points of the day – that is until the late barrage of tries from both sides, Williams' and Skinner's tries adding considerable late drama to this clash, as the sides ended all square.
