The Swans are in stellar form, but with Kurt Tippett's 11-game suspension now over there is every chance coach John Longmire will make three changes to the side that belted Adelaide by 77 points.
Reid has missed two games due to a quad tear, while Jetta was absent from the rout against the Crows due to a shin issue.
"He's going along well now and just needed to unload for a week or two, which he's done and we'll have him running next week leading into the next game," Swans physiotherapist Matt Cameron said of Jetta.
Cameron said the club was also upbeat about Reid being available to take on the Power after the mid-season bye.
"Sam's been out for a couple of weeks and has now started running this week, which is great," he said.
"His rehab plan has him running faster into next week, and we'll make a decision about his training in the second half of the week and whether or not he'll be able to play. We're hopeful that he will."
Both are comfortably part of the Swans' best 22.
Longmire said this week star recruit Tippett was a "strong chance" to play his first game for the Swans.
It's expected the former Adelaide ruck/forward will be rushed into the side, especially with the absence of Shane Mumford.
Mumford underwent surgery on Tuesday to repair a cheekbone fracture and is expected to be out until round 16.
"He had a depressed cheekbone fracture in the game and he did really well to play out the game, but it requires surgery to stabilise it, which was done on Tuesday," Cameron told the Swans' website.
"It really is probably about a four week lay-off."
Lewis Roberts-Thomson (knee) and Rhyce Shaw (abdominal strain) remain long-term propositions for the Swans.
Gary Rohan, still on the comeback trail after breaking his leg in round four last year, is expected to finally return to full training at the beginning of July.
