On a day to forget for the Patriots, Jones had 21-of-30 passing for 213 yards, a touchdown and an interception.
That was only enough to see New England beaten 20-7, their fourth straight defeat to the Dolphins.
Worse was to come with news second-year quarterback Jones required a scan on a back problem, yet Monday brought more positive reporting.
The X-ray was negative, according to widespread reports, while NFL Network suggested Jones had been dealing with back spasms rather than an injury.
Jones was certainly optimistic he would be fit to face the Pittsburgh Steelers this week as he spoke with reporters.
"I definitely feel better," he said. "I want to be ready to play against Pittsburgh. I feel good.
"I wasn't feeling too hot after the game. I definitely feel a lot better. I don't expect any issues. Everything's good."
