He was rendered mostly ineffective by Uruguay’s stout defense; it was fellow veteran Pepe – not No. 7 – whose powerful header pulled Portugal level 10 minutes into the second half after Cavani put the Uruguyans ahead in the first.
I figure level here is like an adverb and pulled Portugal level means pull Portugal back to the competition because of the score by that powerful header. But I don't know if I understand it correctly. What's the correct way of understanding pulled Portugal level in this context?
