Ronaldo : Portugal coach Fernando Santos is likely to rotate his squad, with Renato Sanches, Ricardo Quaresma and Jose Fonte in contention to start.
William Carvalho could replace defensive midfielder Danilo, who is nursing a back problem.
Austria centre-back Aleksandar Dragovic is suspended and could be replaced by Watford’s Sebastian Prodl or Tottenham’s Kevin Wimmer.
Playmaker Zlatko Junuzovic is set to miss out with an ankle problem.
His absence could mean Bayern Munich’s David Alaba operates in an attacking midfield role.
Cristiano would have been hoping to make his mark early at Euro 2016 – and Portugal’s captain did just that following his outspoken reaction tothe 1-1 draw with Iceland. After hastily leaving the pitch, he accused Iceland – population just 332,000 – of negative tactics.
“It was a lucky night for them,” he said. “When they don’t try to play and just defend, defend, defend, this in my opinion shows a small mentality and they are not going to do anything in the competition.”
Portugal attempted 26 shots against Iceland, including 10 from Ronaldo. It is a familiar story for the Portuguese, who often struggle to find a cutting edge. All seven of their qualifying wins were by single-goal margins, and they have also lost friendlies to Cape Verde and Bulgaria recently despite peppering the opposition goalkeeper.
Both Portugal and Austria saw long winning runs end in their opener – Portugal had won seven competitive games in a row, while Austria had won nine.
Austria coach Marcel Koller felt his side made a good start against Hungary – but became increasingly nervous as the game progressed. Koller will need to steady the ship at the Parc des Princes but will have to do so without two key figures – centre-back Aleksandar Dragovic and playmaker Zlatko Junuzovic.
