Derry girl, Una Harkin, faces a race against time to be fit to face England in Northern Ireland's first European Qualifying game against England on Thursday evening.
The match is being billed by the IFA as the biggest game in the history of women's football within Northern Ireland.
Una, who didn't train yesterday morning, was forced to consult the team physio after initially injuring her ankle representing a Northern Ireland select squad in a 2-1 reverse against their Rep. of Ireland counterparts.
Yesterday was the NI women's team's first training session in preparation for their UEFA Qualifier against England on Thursday.
Defender Una who plays with club side Drumahoe YMCA, has won four International caps including her 2006 debut against Turkey and was hopeful of joining the squad yesterday morning.
"I rested for the session this morning," said the 22 year-old yesterday. "Claire (the Physio) hopes to assess me further before the game. Hopefully I'll be fit to play as I definitely wouldn't want to miss this game. We're all really looking forward to the match and everyone wants their chance on the pitch, " said Una.
Manager Alfie Wylie and the squad spent almost two hours at Greenmount Campus on Monday morning focusing on improving sharpness of play, working on movement and quickness of pace etc.
The NI v England match kicks off at 7.30pm, Thursday at Mourneview Park, Lurgan.
