Cape Town - England and Saracens lock George Kruis is expected to find out on Monday whether he requires a second ankle operation in less than a year.
Should he need the surgery, Kruis may be on the sidelines for up to six weeks. His first minor ankle procedure last October kept him out of England’s autumn series.
Kruis's bad luck with injuries saw him also undergo knee surgery in February. However, he recovered quick enough to help Sarries repeat their European Champions Cup triumph as well as win a place on the British and Irish Lions tour to New Zealand.
It is understood that Kruis played with a doubt over his ankle injury when Sarries defeated Northampton 55-24 in their Premiership opener at Twickenham on Saturday. He was subsequently removed from the field after only 14 minutes.
