Tottenham boss Harry Redknapp admits William Gallas is out of the derby with Arsenal.
The former Gunners captain, outstanding in last season's clash, has collected a fresh training ground injury.
"William was looking OK to return but, just when we thought he was over his initial calf injury, he has pulled a calf muscle in the other leg," Redknapp said in The Sun.
"He won't face Shamrock and has virtually no chance of playing Arsenal. It's a shame because he turned in a man-of-the-match performance against Arsenal last season."
