An ankle injury has put Socceroos star Tim Cahill in doubt for Saturday's high profile friendly international against World Cup hosts Brazil in Brasilia.
The New York Red Bulls attacker is awaiting the result of scans on his right ankle, which he rolled early in Saturday's clash with DC United following a tackle by defender Dejan Jakovic.
He was eventually replaced by Frenchman Thierry Henry in the 58th minute.
"When I knocked the ball (in the box), I planted my foot, (Jakovic) got my ankle and I rolled it, and that was it," website soccerbyives.net quoted Cahill as saying.
"I was struggling from then on. It happens, but you get on with it.
"I might be travelling to Brazil, I'll have to see what happens. Shocking tackle, but there's nothing I can do about it."
Cahill later posted a picture of himself on Instragram with a compression machine attached to the injured ankle, lying alongside fellow Australian and Red Bulls teammate David Carney.
Saturday's MLS match was a memorable one for Cahill, who scored his eighth goal of the season and set up another in the Red Bulls' 2-1 victory.
His impressive showing followed an emotional start to the home fixture, with Cahill brought to tears after listening to his 10-year-old son Kyah sing the American national anthem as part of the pre-game entertainment.
"such an emotional and memorable game. My son @kyahtimcahill with an amazing performance of the American national anthem and a great win," Cahill wrote on Twitter.
"Thankyou to all the fans and all the 200plus Aussie fans that attended the game #priceless #RBNY #ourteam".
Kyah is currently studying acting and music in the United States, and has been auditioning for parts on Broadway and with Disney.
