World Cup qualifiers Portugal were held 1-1 at a rain-soaked Windsor Park in Belfast on Tuesday.
A goal early in the second half from Luton Town striker Warren Feeney earned the hosts a share of the spoils after Portugal had gone in front on 40 minutes when Stephen Craigan deflected a Cristiano Ronaldo cross into his own goal.
Portugal could have made it 2-0 just before halftime when record goalscorer Pedro Pauleta whipped a shot past goalkeeper Maik Taylor but his effort was ruled offside.
Northern Ireland, who beat England in a World Cup qualifier in September, hit back after 51 minutes when Feeney headed in a free kick from Sheffield United winger Keith Gillespie.
