Tottenham's injury crisis has deepened after Mohammed Kudus was ruled out for months following scans on his thigh.
Kudus, injured against Sunderland on Sunday, is not expected back until after the March internationals, which effectively means he will not return until April.
Rodrigo Bentancur has suffered a hamstring injury, which Frank admits is 'a bigger one' than they feared. Lucas Bergvall picked up a thigh muscle injury at Bournemouth which needs to be assessed.
Dejan Kulusevski, who damaged a kneecap in May and was initially on course to return in December, has been feeling pain in his recovery training and undergone a course of injections.
