Sydney Swans physiotherapist Matt Cameron confirmed the 24-year-old, who has so far missed ten games with a shin injury, would resume training with the Swans reserves.
Cameron added that Sam Reid, who has not played since he re-injured his quad in round 15, is also a chance to re-join team training on Saturday.
“We’ve got Reid and Jetta out in front and Jetta is definitely going to be training with the team on the weekend in the twos,” Cameron told SwansTV.
“The reserves don’t have a game this weekend so they’ve all put their hand up to train on the weekend with Lewis.
“Sam should train as well.”
Cameron said fellow injured duo Adam Goodes and Lewis Roberts-Thomson were tracking slightly behind Jetta and Reid, but said he expected both dual premiership players to begin training next week.
“Adam and LRT are running at the moment and are increasing their speed and are working on their agility,” he said.
“We’re hoping to have them during team training next week.”
Following last weekend’s 59-point win over St Kilda at the SCG, Cameron confirmed that there were no injury concerns for the Swans from the match.
He said that Kurt Tippett, who was subbed out of the game late in the third quarter, had pulled up well this week after suffering some tightness.
“Kurt was just getting a little bit tight and it was more precautionary, and of course we wanted to get Gary Rohan on and someone had to come off.”
In other injury news, Swans forward Mitch Morton will be available for selection this week following a two-week layoff with a knee injury.
“His knee has settled down and he’s running,” he said.
“He’s due to start training with the team on Thursday so he’ll be available this weekend.”
