JACKSON Trengove will undergo surgery this week after injuring his shoulder during a marking contest at training. 

Although it's a disappointing setback for the key backman, he should return to the running track within 10 days according to Port Adelaide's head of high performance Darren Burgess. 

The 24-year-old, positioned to play his 100th game early this season, will aim to be fully fit for Round 1, given his strong history of injury rehabilitation.

He missed just four games after ankle sugery midway through 2014.

“We expect Jackson should be able to maintain his fitness, to a large degree, as he’ll be able to do most of the team running over the pre-season,” Burgess told portadelaidefc.com.au.

“He does have very good recuperative powers and he does everything right in terms of his rehab so we’re hopeful of a speedy recovery."

Port Adelaide's pre-season got underway at the beginning of January and will culiminate with the NAB Challenge in March. 

It's first public internal trial will take place on Friday 27 February at Alberton Oval.
