Diego Costa was again at the heart of controversy after he appeared to strike defender Leonardo Bonucci in the face during Spain's 1-1 draw with Italy in Turin.
In a replay of their Euro 2016 last 16 clash, Spain looked to have the match wrapped up after Vitolo capitalised on a Gianluigi Buffon mistake to slot home in the 55th minute.
However, Sergio Ramos hauled down Eder with eight minutes to go, allowing Daniele de Rossi to coolly slot home for a share of the spoils.
But the headlines were taken by Costa after his clash with Bonucci. The Chelsea striker was fortunate not to be sent off anyway when, on a yellow card, he kicked the ball away after conceding a free-kick - a decision that led to his hasty withdrawal by coach Julien Lopetegui.
In Wales and the Republic of Ireland's group, Serbia notched an expected 3-0 win in Moldova with Chelsea's Branislav Ivanovic and Southampton's Dustin Tadic both on the scoresheet.
Elsewhere, Kosovo are still looking for their first points as a footballing nation following their 6-0 loss to Croatia.
Mario Mandzukic netted a hat-trick for the Croatians, who eased to victory over the Group I minnows.
Iceland scored twice in injury-time to record a 3-2 win over Finland in Group I, with Ragnar Sigurdsson's 95th-minute strike proving the difference.
Turkey and Ukraine shared the spoils with a 2-2 draw, Israel won 2-1 away at Macedonia and Albania defeated Liechtenstein 2-0.
