Manchester United forward Alexis Sanchez is likely to be out for four to six weeks with a knee injury.
Manager Ole Gunnar Solskjaer confirmed the news as United flew out for tomorrow's second leg of their Champions League last-16 tie with Paris St Germain.
The 30-year-old's Old Trafford career hit its latest roadblock as he was forced off early in the second half of Saturday's 3-2 Premier League win against Southampton.
Chile physio Pedro Onate said Sanchez would be "unavailable to play for between six and eight weeks."
Solskjaer told a press conference: "It was a bad knee injury so if it's four weeks or six, hopefully he'll recover quickly."
