Belfast Harlequins welcome back Irish international Lizzie Colvin for Saturday's crucial EY Irish Hockey League clash with Ards at Londonderry Park.
Colvin, who was included in head coach Graham Shaw's World Cup training panel last week, missed the weekend 2-1 Irish Senior Cup win over Pembroke with a minor injury.
However, she has now made a full recovery and will play a key role in all-Ulster clash with Ards.
Neither side has given up on a place in the end-of-season play-offs for which a place in the top four after the regulation campaign should be sufficient.
Provided either holders UCD, Cork Harlequins or Pegasus go on to lift the Irish Senior Cup and remain in the top three positions, an extra slot will be freed up for the play-offs.
Ards are just two points ahead of Harlequins, who have a game in hand, so if Davy Frazer's side can win on Saturday, they would be in with a better chance of making the top four.
The Quins coach is obviously glad to have midfielder Colvin back on board for such an important game but, at the same time, he was happy how the rest of the players responded on Saturday.
The Deramore side also added Colvin's international colleague to their squad in the summer and are now reaping the benefits of their marquee signings.
Frazer said: "Zoe and Lizzie have made a big impact both on the pitch and off it with their ability and leadership qualities.
"But when we have been without them, the other players have really stepped up.
"Schoolgirl Rhiannon Coulter played really well on Saturday and was involved in the build-up to the winning goal.
"Of course, we might sneak in to the play-offs if we win the Irish Senior Cup."
Pegasus, however, remain Ulster's best bet for a place in the shake-up as they are currently three points clear of Railway Union in third place in the table.
On Saturday, they play their final out-of-province game when they travel to Dublin to face Loreto, who haven't given up on a play-off place.
Pegasus hope to have Irish international Michelle Harvey available again after she missed the 2-1 home loss to Cork Harlequins a fortnight ago.
Also on the all-Ireland front, Mossley host Bray in the semi-finals of the Irish Hockey Trophy following their dramatic penalty shoot-out win over Cork C of I at the weekend.
