Manchester United defender Rafael da Silva could be out for a month with a hamstring injury sustained during Sunday's Community Shield win.
The 23-year-old pulled up with the problem during the 2-0 victory over Wigan Athletic at Wembley, limping off after just 16 minutes to be replaced by Chris Smalling.
And after watching United secure their first piece of silverware this season courtesy of a brace from Robin van Persie, the Brazilian fears he may be set for a spell on the sidelines.
When asked for his feeling about the injury, he said: "A hamstring, I could be out four, five weeks."
Manager David Moyes was not quite as concerned, though, with Rafael having to miss the Premier League opener against Swansea on Saturday through suspension anyway.
"Rafa said that he felt his hamstring and in a game like this when you have an opportunity to make substitutes, it was fine," the Scot told MUTV.
"He is suspended for the first game of the season anyway, so in a way, I wouldn’t say it doesn’t matter but it won’t have an effect on what we do next weekend."
