GREATER Western Sydney will turn to two debutants to help cover its massive injury toll, with Caleb Marchbank and Jack Steele locked in for Saturday's clash against North Melbourne. 

Marchbank, who was recruited with pick No.6 in last year's NAB AFL Draft, will slot into the Giants' backline after Phil Davis (ankle) and Joel Patfull (ribs) were sidelined for up to two months.

Steele, meanwhile, will replace injured midfielder Stephen Coniglio (AC joint) after impressing since joining the club as a product of its talent academy.

The 19-year-old was recruited with pick No.24 in last year's draft after the Kangaroos bid their first selection for the Canberra product.

"Jack will probably play forward and midfield as well, he's been playing that role at NEAFL level," coach Leon Cameron said on the club's website.

"He’s been playing some tough on-ball footy for probably six or eight weeks now. 

"He’s a real competitor so really wherever he lines up, it doesn’t matter, you know he’s going to put his head over the footy and tackle really hard and that’s what we want to be known for."

Steele has had a string of best-on-ground performances for the UWS Giants and has been named an emergency at AFL level five times this season. 

Marchbank, 18, has also enjoyed strong form in the NEAFL as a key defender.

"Caleb’s been playing a key back post for the last eight weeks, whether he’s been that second tall or third tall," Cameron said.

"He’s a terrific young kid, he’s got a really competitive attitude. He likes to fly for his marks, he spoils really well. He’s very courageous in the air and his performances have been getting better and better.

"Bringing in these two young kids that are competitive players, can hopefully help us with that contested ball."
