Aston Villa boss Dean Smith has been forced to miss the club's first pre-season match of the summer as he isolates with his family.
His absence for the game against League Two side Walsall was confirmed just 90 minutes before kick-off.
Smith's assistant Craig Shakespeare was put in charge for the match at Banks's Stadium - the first of Villa's five pre-season friendlies.
The Premier League club did not release any more details about Smith's absence.
