Young GIANTS ruckman Matt Flynn has torn the anterior cruciate ligament in his knee during Saturday night’s win over the NT Thunder at TIO Stadium in Darwin.

Going back with the flight of the ball into a marking contest, Flynn’s knee twisted with subsequent scans revealing a torn ACL which will sideline the 21-year-old long-term.

It’s a disappointing blow for the young ruckman who has been named as an emergency several times this season and recently signed a two-year contract extension.

“It’s devastating for Flynny,” GIANTS General Manager of Football Wayne Campbell said.

"He’s developed each year, each game and each month really that he’s been at the football club and had been really close to senior selection. 

“He went down, stepped on the back of Jye Caldwell’s leg and hyperextended it. It was a bit like Stephen, we were hopeful with the diagnosis of the physios and doctors on Saturday night but he had scans yesterday and he’s ruptured his ACL.

“Certainly our thoughts go out to him. We’re not having a great run at the moment but we’ll rally around Flynny and the rest of our boys and get on with it after that.”

Small forward Langdon will also be sidelined for eight weeks after surgery on his ankle late last week.

After a stellar debut season in 2018, the former electrician has battled foot and ankle injuries this season to play just three games.

“He had a syndesmosis injury so he’s had a tightrope put in there and they tend to be about eight weeks,” Campbell said.

“The season’s not over for him. He’ll get back and start training and hopefully we’re still deep into the finals and he can make an appearance then."

As revealed on Monday afternoon, vice-captain Stephen Coniglio has avoided an ACL injury but will undergo surgery today on his knee.

The star midfielder is expected to be sidelined for around eight weeks and is still a chance to return to the field later in the season.

“It’s strange when you’re punching the air when you get a prognosis that he’s going to be eight weeks but obviously the night before we thought it might’ve been a little bit worse than that,” Campbell said.

“He had surgery this morning and had some cartilage taken out so it’s been a pretty good result. It looks like about eight weeks, where it’s seven or nine will depend on how he’s going. 

“It will be slow at the start and then he’ll get his quad strength up and start running about the four-to-six weeks mark and hopefully be around that eight-week mark.”

Ruckman Shane Mumford also looks set to return this weekend after two weeks on the sidelines with soreness.

“He’s certainly available for selection,” Campbell said.

“The two weeks off has done him a world of good. He’s had that sore knee, sore foot and sore older body but the two weeks off has been good for him and he’ll be available for selection this weekend.”

The GIANTS take on Collingwood at GIANTS Stadium on Saturday at 4:35pm.
