Maynard ended the thrilling two-point win on the interchange after a collision with Crow Izak Rankine in the dying stages of the match, with the Magpies defender left on his knee and clutching his shoulder on the sidelines.
The marking contest left Maynard winded and with a blow to his ribs, while concerns surrounding another shoulder injury to the All-Australian were also thrown into the mix.
The 26-year-old hasn't required scans on the ailment, with Maynard revealing he remains in the mix to play in Round 16 against the Suns.
"It's not too bad, I'm a little sore," Maynard told 9 News on Monday.
"It was a bit of a weird one. I got winded, hit in the ribs and then my shoulder popped backwards.
"I've done multiple shoulder (injuries) over the last couple of years and over my career, so I know when it's back and I know when it's alright.
"I should be fine."

The Magpies have a six-day turnaround for their clash at Carrara on Saturday, where Craig McRae's side will be hoping to extend their winning ways as the competition's ladder leaders.
Collingwood are close to having a fully fit side to select from, with forward Dan McStay nearing a return after a recent setback to a finger injury that has kept him out of action since April.
The Magpies will face the Suns at Heritage Bank Stadium on Saturday afternoon at 4:35pm (AEST) as they search for their 13th win of the year.
