Center DeMarcus Cousins fully participated in Team USA's practice Tuesday after sustaining a knee injury during a scrimmage last week, according to John Schuhmann of NBA.com.
An MRI revealed no structural damage on the knee, but Cousins was held out of Saturday's scrimmage against Brazil in Chicago.
Team USA lacks depth in its frontcourt after Paul George suffered a gruesome leg fracture and Kevin Durant elected to withdraw.
The team's remaining forwards besides Cousins are Kenneth Faried, Mason Plumlee, Anthony Davis and Andre Drummond.
