Tottenham Hotspur manager Mauricio Pochettino could be without a recognized right back when his side plays Arsenal on Sunday in an English Premier League match.
Kyle Walker-Peters might not recover in time for the North London Derby, after suffering an injury during the club's 1-0 loss to Newcastle last weekend.
It was expected that the youngster will be out for only a few days and could make it for the derby, but he is running against time for the crunch fixture.
Walker-Peters has started all the three Premier League match, having been drawn into the side following Kieran Trippier's move to Atletico Madrid.
Juan Foyth could have offered Pochettino some cover, but he is currently missing from the side due to an injury, and will only make a return after the international break.
Serge Aurier is the only option left for the Argentine at right-back, but with the Ivory Coast international expected to complete a move away from the club, he might be left out for obvious reasons.
Spurs will be hoping to bounce back from the Newcastle defeat, which came after a hard-fought 2-2 draw against Manchester City the previous week.
Their opponents, on the other hand, will be keen to put their 3-1 defeat to Liverpool behind them, and with the bragging rights at stake, the will be keen on picking the three points.
