The midfielder has since returned to Milan on loan to boost his chances of making England's World Cup squad after a successful stint at the Italian club last season.
The club's doctor, Massimo Manara, reported on Tuesday that Beckham is now in fine fettle after his second day of training since returning to the Serie A side.
Manara told the club's in-house television channel: "I found David Beckham really well.
"Even though a year has passed, he looked to be at the same level as a year ago to me.
"The problem he had with his right foot in previous weeks is resolved."
