Betts was hit with a five-match ban for the collision but his six-year good record and early plea reduced the sanction to three.
The Saints confirmed on Tuesday that Wright - playing in his fifth senior game - would be sidelined.
Earlier that day, the team recovered at the Linen House Centre in Seaford in a buoyant mood following their second win of the season.
Young midfielder Seb Ross said a pleasing aspect of the nine-point victory against Carlton was the fact the younger players stepped up.
"What the older boys have been showing over the past few weeks has been outstanding leadership and how to really play the game," Ross said.
"It was good for the younger boys to step up and play their role this week with a few older players out.
"It was a big reward for effort. The past few weeks have been good and we've been building and building, and it was good to finally get the win."
Jimmy Webster was the Saints' fifth debutant on Monday night and was substituted on for the injured Wright for a return of nine disposals.
Ross said the performance of players like Jack Steven, who had 39 possessions, was an indication the club's younger players were up for the challenge of stepping into the shoes of absent veterans.
"With blokes like Lenny Hayes out of the side, us younger boys had to take a fair bit of ownership and step up our game," he said.
"I think for the younger boys to get an opportunity in the senior side they have to show things at VFL level so when they come into the side, they have the coaching staff and the players' trust to play their roles.
"We've still got the great older players around us but we've got a good batch of younger players coming through, which is pretty exciting for the club."
He said he had been building on his own game this season after coming into the side in round four and holding his spot since, following on from his debut in round 22 last year.
Ross had 21 disposals and considered the game his best at AFL.
"I've been trying to play my role for the team and if I continue to play my role other things will come," he said.
"I had to work on the defensive side of the game, my tackling pressure. I think I got that right this week, which is what I thought was best.
"You're pretty nervous for your first couple of games but once you get the confidence from the coaching staff that you're meant to be out there, you can build on that."
