The Manchester City striker Sergio Aguero will know in a couple of days whether the knee injury sustained in the opening 3-2 English Premier League football win at home to Southampton today is serious.
The Argentinian striker, whose last-gasp goal against Queens Park Rangers sealed the title for City in dramatic fashion back in May, was carried off on a stretcher after 13 minutes.
City's top goalscorer last season looked in severe pain after a tackle before getting to his feet and then dropping to the floor again.
Manager Roberto Mancini says they'll need to wait two days for the scan.
Any long-term absence for Aguero will be particularly agonising for City having missed out on striker Robin van Persie, who opted for Manchester United after leaving Arsenal.
A dip into the market with two weeks left in the transfer window is always possible for the club, although City proved they have goals throughout the team in the comeback win over promoted Southampton.
In scenes reminiscent of May's title triumph against QPR, Carlos Tevez, Edin Dzeko and Samir Nasri scored as City came back from 2-1 down to win late on.
