A late Matias Fernandez goal confirmed Sporting's passage into the last 16 of the Europa League at Legia Warsaw's expense.
The Lisbon side went into the tie leading on away goals after the 2-2 draw in Poland last week.
In a dull first half neither goalkeeper was called into serious action.
The second half picked up a little but chances were still at a premium in a low-quality game.
Chilean midfielder Matias Fernandez finally settled the home fans' nerves when his whipped cross from a free kick eluded everybody in the box, including the goalkeeper, and ended up in the back of the net.
Sporting goalkeeper Rui Patrício was called into late action to prevent an equaliser Legia probably deserved, but it is the Portuguese team who make progress.
The Lions will now play Manchester City in the last sixteen, with the first leg taking place in Lisbon.
