Gallas gives Spurs defensive boost
Gallas missed Monday's 2-1 defeat against Norwich City with a calf problem, but the French centre-back is set to return to action this weekend against his former club.
"I'm fit to play again and I'm coming back to the squad," Gallas said on Friday.
The 34-year-old, who last featured at Sunderland on 7 April, could go straight into the starting line-up at Wembley as Redknapp has been hit by defensive injuries.
Michael Dawson is out for the rest of the season, while Younes Kaboul is struggling with a knee injury suffered against Norwich.
That leaves Gallas, Ledley King and Ryan Nelsen as Redknapp's only fit central defenders.
