Edgar Davids and Teemu Tainio face late fitness tests before the Premiership derby at White Hart Lane.
The hairline fracture of the fibula that Edgar suffered against Aston Villa has healed and he's doing all he can to make it for the televised encounter kicking off at 1.30pm.
Teemu picked up an ankle injury against Villa and looks the more likely of the two to recover in time.
"Edgar will have a late test tomorrow," said Head Coach Martin at Friday's pre-match press briefing. "There is a hope he will play.
"He's 32 and he knows exactly when he can play and when he can't play.
"He said he will try to play and he tried today, but he didn't look 100 per cent. We'll work on him and hopefully he will be better on Saturday but I think he has to be a big doubt for Sunday.
"He has been able to train because he wants to play but I don't think he's right yet. The fracture has healed and it's all about whether or not it's too painful and if he can play with the pain, it will be okay.
"Teemu still has a bit of a problem with his ankle but he's making good progress."
