The midfielder was left clutching his knee during the first half of the Clarets' defeat to Leicester City following an awkward but accidental collision with his former Hull City team-mate Harry Maguire.
Robbie Brady is to undergo knee surgery and faces a "substantial" time out of action.
BURNLEY have confirmed that Robbie Brady will undergo knee surgery after the Ireland star suffered damage to his patellar tendon.
Brady went down in the 31st minute of the loss at the King Power stadium on Sunday and, after extensive treatment on the field of play, was stretchered off to applause from all corner of the ground.
This is a very serious injury and recovery time usually lasts between four and six months.
Heartbreaking news given the form that Brady has been in of late but we're sure he will be back stronger than ever in time for next season and Ireland's participation in the newly formed UEFA Nations League.
Stephen Ward, Brady's club and global teammate, says the effervescent midfielder's absence "will be a massive loss" at Turf Moor.Burnley's next run of fixtures until the New year is as follows: Watford, Stoke Brighton, Tottenham, Man United, Huddersfield.
He had made 15 appearances for the Turf Moor club before this unlucky break.
Sean Dyche has also been speaking about Brady's injury on Wednesday.
