Vesty gives latest on injured trio ahead of Saints' game against Gloucester
and live on Freeview channel 276
Furbank was forced off inside the first 15 minutes of the match against Sale Sharks last weekend and he couldn't put any weight on his right leg.
But it appears the 26-year-old has avoided a serious issue.
"He had a scan and it came back with nothing major wrong there so it's about managing him back into the fold," said Vesty. "We're not too worried."
Fly-half Fin Smith was another player who had his outing cut short during the 38-34 win last weekend.
Vesty said: "He picked up a dead leg and it will be about managing him back into training this week.
"It's been a bit of a brutal toll on the bodies this week but sometimes you have it where you've got to look after the guys in the early parts of the week."
However, it seems scrum-half Tom James will be out for a period of time.
Youngster Jake Garside, who has been on dual-registration at Bedford Blues, is the likely candidate to provide back-up for Braley.
"He (James) is struggling a little bit more with a bad shoulder and he'll be out for a little bit of time," Vesty said.
Saints will get a key player back this week though as Lukhan Salakaia-Loto is now free from the suspension he picked up for a red card against La Rochelle last month.
Mitchell, Courtney Lawes and Lewis Ludlam are with England, but David Ribbans, Fraser Dingwall and Tommy Freeman have been sent back so they can play against Gloucester.
