The 26-year-old — part of England’s World Cup squad and who made his international debut against Costa Rica earlier this year — had to go off after a collision with Aberdeen striker Sam Cosgrove.
“Nick has gone to hospital and it certainly looks more serious than not serious at this stage,” said Dyche.
“It was a bit of a needless challenge.
“When he responds to stop the ball going in I think the lad has caught his arm and knocked it back, so we’ll just have to wait and see.”
Dyche’s side — appearing in European competition for the first time in over 50 years — had to come from behind to secure a 1-1 draw in the Europa League qualifier first leg clash.
