- James Sicily, who broke Dogs' hearts in round three, is back

- Toby McLean wins the race to replace injured Bulldog Lin Jong

- Defender Jeremy Laidler returns for hamstrung Callum Mills

HAWTHORN has added some firepower and pace for Friday night's semi-final against the Western Bulldogs, bringing back forward James Sicily and speedy wingman Billy Hartung for the do-or-die MCG clash.

Sicily, who sunk the Bulldogs with the match-winning goal in a three-point thriller at Etihad Stadium in round three, returns after missing last week's qualifying final loss to Geelong due to illness.

Hartung gets the opportunity to cement a spot after being dropped for the Cats clash despite playing 17 games this year.

The 21-year-old was also omitted for last year's Grand Final triumph and was axed before Hawthorn's successful finals campaign in 2013.

First-year utility Ryan Burton misses out after suffering a corked calf last Friday night, while half-back Daniel Howe has been dropped after coming in as a late replacement for Sicily last week.

Tough defender Taylor Duryea has been named despite a hand complaint as the Hawks seek to keep their historic bid for four straight premierships alive.

Hard nut Will Langford, premiership backman Matt Spangher and Howe are Hawthorn's emergencies.

The Bulldogs have been forced into one change after their 47-point mauling of West Coast, with Lin Jong (broken collarbone) going out and second-year midfielder Toby McLean earning a call-up.



It will be McLean's second senior match since round 11 after working his way back from a mid-foot sprain.

Ruckman Tom Campbell, Roarke Smith and Lukas Webb round out the 25-man squad.

Veteran defender Ted Richards, who will retire at the end of the season, is one of the Swans' emergencies alongside James Rose and Harry Cunningham.
