Tottenham have confirmed that manager Harry Redknapp will undergo minor heart surgery today and will therefore be absent when Spurs face Rubin Kazan in the Europa League tomorrow.
Redknapp will not travel to Russia with the squad so Kevin Bond and Joe Jordan will take the reins in Russia.
A statement on Tottenham's website read: "The club can report that Harry Redknapp is due to undergo a medical procedure tomorrow morning and will therefore not travel with the squad to Russia for our Europa League fixture against Rubin Kazan.
"Kevin Bond and Joe Jordan will assume first-team responsibilities in Russia in his absence."
The club have not revealed whether Redknapp will return for Sunday's Premier League clash with Fulham.
Tottenham take on Kazan with a two-point lead at the top Europa League Group A.
