The defender had to be taken off on 55 minutes during Manchester United's 0-0 draw with Hull at Old Trafford.
Jones left the field holding his right boot in his hand as he limped down the tunnel with fans fearing it could be a lengthy spell on the sidelines.
But the 24-year-old says he should be fine in a few days and is expecting to be in contention for United's trip to Leicester on Sunday (4pm).
"My foot's bruised but I'll be fine," he told MUTV after the match.

"It's nothing sinister, nothing serious, so hopefully in a few days I'll be fine."
United failed to make the breakthrough against a resilient Hull defence to close the gap on their rivals at the top.
Zlatan Ibrahimovic, Paul Pogba and Juan Mata all had decent chances but goalkeeper Eldin Jakupovic was equal to them.
And Jones admits the Switzerland international's heroics were frustrating for his team.
He added: "I think if we had scored in the first 20 minutes, then you couldn't have seen much of a way back for Hull with us 1-0 up, creating chance after chance. But we just couldn't get that goal.

Who impressed for Manchester United against Hull?
Jose Mourinho wasn't happy with his team's performance against the Tigers
"Their keeper pulled off an absolutely heroic save from Juan [Mata, in the second half]. There's nothing you can do.
"We've said it so many times this season that a goalkeeper has come here and been world class. But listen, it's no excuse. We needed to win the game. We've not won the game.
"All we can do now is look towards Leicester on Sunday. Thank God it comes around quickly because we can try and put things right again."
Manchester United remain sixth in the table, four points behind fourth-placed Liverpool.
