SYDNEY'S joy at being one win away from this year's grand final has been soured by a hamstring injury to midfielder Ben McGlynn.
McGlynn was visibly upset as he sat on the bench after breaking down in the third quarter of the Swans' stunning upset over Adelaide at AAMI Stadium.
Swans shock Crows in qualifying final
Sydney convincingly defeat Adelaide by 29 points in the qualifying final at AAMI stadium.
The former Hawk will have scans tomorrow or Monday to find out the severity of his injury but with 21 days the standard recovery time for a hamstring injury, he would be at long odds to take part in the preliminary final in a fortnight.
It is a cruel blow for McGlynn, whose toughness and nous around goals have added an extra dimension to the Swans in recent seasons.
His woe was in contrast to the excitement in the Swans dressing room as they celebrated an unlikely 29-point victory over a side they had beaten just twice in their previous 14 matches.
It leaves them within reach of a grand final berth many thought was beyond them after they lost three of their last four home-and-away matches and the services of key defender Heath Grundy to suspension.
But coach John Longmire was guarded when asked whether the Swans could emulate the class of 2005 and win the flag.
''It's a fair way off,'' he said. ''We're fortunate now we're in a position where we can sit back and plan and prepare for a home preliminary final in two weeks, and that's all I will be focusing on.''
Longmire paid tribute to Adam Goodes, who rediscovered his best after a quiet run since recovering from injury in June.
''His first half was outstanding,'' he said. ''As captain and someone we look for to stand up in big games, he did that and he was huge; it really lifts the entire side.
''We knew it was coming with Adam. He's received some criticism outside the footy club. We knew his work rate is second to none.
''The way he started, he was involved in a lot of our scores and he understood the tempo of the game really well.''
Gun ball-winner Josh Kennedy hailed the win as Sydney's best in recent years.
''In the context of what was on the line and the position we're in and now the opportunity we've given ourselves, as long as I've been here it's been the most valuable win, for sure,'' he said.
The seven days off could prove decisive for the Swans, many of whom were last night nursing aching bodies.
''It was a real hard-hitting, tough game and [we're] really feeling the effects now,'' Kennedy said.
''We've got a lot of sore bodies [but we'll] enjoy the week off and look forward to the prelim in Sydney. It's a bit surreal.''
