Leeds' young Brazilian missed the 3-1 defeat at Cardiff on Saturday through injury.
The Brazilian was ruled out of Leeds' trip to Wales, which ended in a 3-1 defeat during Neil Redfearn's first game as the club's permanent manager.
Alex Mowatt produced an impressive display for the Yorkshire side, scoring their only goal of the game - but Russell Slade's men had far too much for Leeds in the end.
Redfearn could have done with 20-year-old Adryan, who has impressed in the brief spells he has been given so far during his Elland Road career.
It was not to be, however, although the Brazilian has allayed fears over his injury, reassuring fans that it is 'nothing serious.'
Thank u everyone! Nothing serious, just a precaution.. I'm sad with the defeat but we can't forget the next game against Charlton. #workhard— Adryan Tavares (@adryantavares) November 1, 2014
Leeds host Charlton on Tuesday evening, who are currently 9th in the Championship.
Redfearn's men, by contrast, sit 19th in the table after their Cardiff defeat, largely thanks to a terrible time under sacked managers Dave Hockaday and Darko Milanic.
