Sue Smith was once again unavailable for selection following a calf injury.
The playmaking midfielder has been on the sidelines for Doncaster Belles since last March after enduring a career-threatening injury in her first game for the club.
She was unavailable for Doncaster’s 2-0 FA Cup fifth round defeat at home to Bristol Academy following her latest injury she sustained recently.
However, it is hoped the 33-year-old will be back in the Belles’ line-up for Chelsea on Saturday.
“Sue picked up a calf injury last week and we had hoped it would be okay for the Bristol game,” said Buckley.
“We badly missed her on Sunday, she would’ve provided that little bit of magic between the midfield and Jess Sigsworth up front that could have made the difference.
“But hopefully she’ll be back against Chelsea.”
Doncaster Belles welcome Chelsea to the Keepmoat Stadium on Saturday in the Continental Cup. Kick-off is 6pm.
