HAWTHORN and the Sydney Swans must solve important selection issues as they try to rebound from their qualifying final losses.

Last year's grand finalists will confront less battle-scarred opposition when the Hawks play Adelaide and the Swans host North Melbourne in the semis.

Hawthorn have to find a replacement for forward Jack Gunston, who injured his ankle in last Friday night's loss to West Coast.

The Swans' injury woes worsened when key forward Sam Reid suffered a hamstring injury against Fremantle, ending his season.

The teams will be named at 6.20pm on Thursday evening.

Swans coach John Longmire added this week that Lance Franklin's health problems meant he also would not play again this year.

In better news for the Swans, Nick Smith is set to return and co-captain Kieren Jack might also be a surprise recall for Saturday night's match at ANZ Stadium.

North emerged from last Sunday's elimination final win over Richmond with no major injury problems.

Jamie Macmillan rolled an ankle, but he is expected to play.

And the Kangaroos remain hopeful that Daniel Wells will return during the finals, despite only managing two senior games this season.
