Spain defender Diego Llorente has tested negative for Covid-19 and could rejoin training on Friday.
Leeds' Llorente and captain Sergio Busquets tested positive this week, leading to Spain's Under-21 squad playing their friendly against Lithuania on Tuesday, winning 4-0.
Llorente tested negative on Wednesday, leading Spain's FA to suggest his first test may have been a false positive.
He could return to training on Friday if further tests are negative.
Spain host Sweden on Monday at 20:00 BST in Seville.
