Davide Somma ensured a point for Leeds a minute after stepping off the substitutes' bench at Portsmouth in a 2-2 npower Championship clash that was twice halted by floodlight failure.
Leeds manager Simon Grayson sent on Somma for Sanchez Watt straight after Pompey had regained the lead through John Utaka against the run of play in the 61st minute, and the striker equalised with his first touch.
Portsmouth had made the better start and led 1-0 at half-time thanks to Joel Ward's 26th-minute strike.
But the visitors, determined not to let their midweek FA Cup exploits distract them from their promotion push, levelled through Luciano Becchio two minutes into the second half.
Portsmouth fought back from 3-1 down to clinch a point at Elland Road at the end of December, but lost their next three league games and were dumped out of the FA Cup at Brighton, so a point to keep them five clear of the relegation zone was met with relief.
