Weston McKennie will not return to action for Juventus until next season, head coach Massimiliano Allegri has confirmed.
The United States international fractured the second and third metatarsals in his left foot during last week's 1-1 draw with Villarreal in the Champions League.
Juve announced the following day that McKennie would likely sit out the next eight weeks, meaning he would be back in time for the closing stages of the campaign.
However, speaking after Juve's 1-0 win over Spezia on Sunday, Allegri said he does not expect the 23-year-old to return to action again this term.
"The season is over for Weston because of his injury. He'll be back next season," Allegri told DAZN.
McKennie has featured in 28 of the Bianconeri's 39 matches this season in all competitions, his 1,954 minutes on the field the eighth most of any Juve outfield player.
The 23-year-old, who has four goals to his name, will also miss the USA's upcoming triple-header of World Cup qualifying fixtures.
Juve won in McKennie's absence against Spezia on Sunday thanks to Alvaro Morata's 21st-minute strike at the Allianz Stadium.
Morata slotted home the only goal of the game after being played in by Manuel Locatelli – the Spain striker's first Serie A goal since netting against Bologna on December 18.
The victory extends Juve's unbeaten run to 14 Serie A matches – their best such streak since March 2019 when going 31 without defeat – and tightens their hold on fourth place.
"It's always important for the forwards. I'm happy with the goal and the performance," Allegri said at his post-match news conference when asked about Morata's goal.
"Today, after so many matches with the same players, all you have to do is congratulate the boys. It wasn't easy to win. We dropped in the second half.
"For the first time we are mathematically fourth in the rankings. In the first half we had to finish the game, in the second it was normal that we would suffer a little."
Juventus have now won four Serie A matches by a 1-0 scoreline this season, a tally only sixth-placed Roma can better with five.
And the manner of this latest slender victory was particularly pleasing for Allegri.
"If you want to reach your objectives, you have to play these games with suffering and it was important to bring home the three points," he said.
"I have never seen a team win every game easily. You get to the Champions League and all your targets through performances like this, winning 1-0 with suffering.
"People forget quickly in football, but in my five years we had a lot of 1-0 results spent sitting in our own half for the final 20 minutes.
"The important thing is not to let anything go in those moments."
