Pompey were at their battling best to secure a 2-2 draw with Doncaster on home soil.
Rovers twice forged ahead through James Coppinger and John Marquis, but first debutant Anton Walkes and then substitute Brett Pitman drew them level.
An injury to Stephen Henderson meant that, with all three changes made, Kal Naismith had to go on goal for the closing stages.
And the hosts survived with just nine men when Christian Burgess was sent off for a second bookable offence in stoppage-time.
