Women's World Cup Qualifier: Northern Ireland hit by Furness injury blow after loss
Scotland 2 Northern Ireland 0: Northern Ireland will try to beat Bosnia on Wednesday night without their biggest attacking threat.
Striker Rachel Furness limped out of Saturday night's opening World Cup qualifier against Scotland, which Northern Ireland lost 2-0 and now she faces a race against time to face Bosnia at Mourneview Park.
Jane Ross capitalised on a poor kick from Northern Ireland goalkeeper Emma Higgins to give the Scots an early lead and Jennifer Beattie struck 12 minutes from time to secure the win.
In between, Sarah McFadden had come close to equalising for Northern Ireland when her header flew over the crossbar.
"It was a soft goal to give away, but it was hard after that against a top side and if we'd kept it 0-0 for longer we might have got something out of the game," said Wylie.
"At this level and against a highly ranked team like Scotland, you will get punished for silly mistakes.
"We lost Rachel Furness after 15 minutes as well and with Simone Magill already out it really hurt us attacking wise.
"We'd a good chance through Sarah McFadden just before half time and if we'd gone in at 1-1 we could have had a go at them."
Furness will undergo intense treatment over the next 48 hours in an attempt to be fit to face the Bosnians.
"Bosnia only lost 1-0 to a penalty against Sweden and they will be difficult to beat," said Wylie.
"They've had a couple of games, whereas Saturday was our first since July and first competitive match in a year."
