A new bout of tendinitis has scuppered his return to training with Saracens and put his inclusion in England's June tour to Australia and New Zealand in doubt.
It has been revealed today that the lock needs another two months of conditioning and rest to return to full fitness.
Bothers was targeting a return against Leicester this Saturday - a match which could dictate if Sarries will grab a home semi-final.
But has his absence been a bad thing?
Some of his critics have linked Borthwick's stint on the sidelines with Saracens' recent impressive and explosive play. Sarries have been doing very well without him, thank you very much, and England seemed to cope just fine in his absence.
OK, so England lost to France, but under skipper Lewis Moody they were a much hungrier and dynamic force.
So with one of England's first choice second rows laid up, it looks like there'll be a space in the starting line-up.
Cometh the hour, cometh the man. The World Cup is but months away.
