The 21-year-old winger only moved to the Dutch outfit on deadline day last month but is now back at Stamford Bridge.
Belgian U21 star Musonda damaged his shin in a behind-closed-doors game with Royal Antwerp on Saturday.
He was forced off just before half time and will now be hoping Chelsea's medics do not discover the damage is long-term.
And Vitesse will also have their fingers crossed the ace is not ruled out for a lengthy period.
The Eredivisie side have already lost Dane Rasmus Thelander to a broken ankle this season.
