Roos coach Matt Dunn said early indications were Uebergang had torn his anterior cruciate ligament in the 20.13 (133) to 12.6 (78) defeat at Melville Oval on Saturday night.

Uebergang had kicked two goals in the Pride and Inclusion Game – an initiative designed to promote acceptance around sexuality –  before he was hurt in the third term.

“It didn’t look good when he came off and the medical staff said ACL,” Dunn said.

“He did it two years ago too.”

The injury added to the Kangaroos’ woes. They were 63 points down at half-time.

The Roosters piled on 13 first-half goals to ensure 100-game players Kym Eagleson and Sam Thompson would celebrate their milestones in style.

Key defender Eagleson, who recently moved to Mount Gambier to work for company International Timber Solutions, said the Roosters’ fast-start was pleasing.

“We were sharp with our hands in the first half,” he said.

“We were mindful of the fact it could be quite dewy, particularly after half-time.

“It was a little bit disappointing in the second half but Hamilton played well.

“All in all we went up and got the job done. Week-by-week we have to keep ticking the boxes.”

Thompson, 25, said he was happy to notch a miletsone at South Warrnambool.

“I’ve been lucky because I had a couple of shoulder recos when I was 16 and 17 so I didn’t think I’d play any senior footy,” he said.

“I’ve dislocated it a couple of times since then but nothing too major.”

South Warrnambool coach Mathew Buck, who rated midfielders James Hussey and Jock Blair and ruckman Manny Sandow as its best, was thrilled with the Roosters’ mindset.

“We came out with a real intensity and willingness to compete,” he said.

“I thought we pressured them and took away their time and space well – we denied them what they wanted which was a focus for us.”

Dunn conceded the Kangaroos struggled to negate the Roosters’ run.

“They had slick ball use and their first four goals came from our turnovers,” he said. “We outscored them in the second half which was pleasing because at half-time there wasn’t a lot happening for us.”

Darebin Falcons scored a thrilling 5.4 (34) to 4.4 (28) win over Melbourne University in the VFLW  curtain-raiser.

“The day itself was huge. There was people everywhere and it was a big day for the club and the town,” Dunn said.
