Taylor has lost his starting spot with the Trotters following the summer arrival of Martin Petrov from Manchester City.
At a time when Coyle admits he needs to release players if he is to bring any more into the Reebok Stadium ahead of the August transfer window closing, the 28-year-old has been mentioned as one of those who might make way.
However, ahead of Tuesday night's Carling Cup trip to Southampton, Coyle has assured Taylor he still has a major role to play at the club.
"Matty Taylor is a fantastic player who has had an unbelievable Premier League career," said Coyle. "He is frustrated at the moment because he has been on the bench and Martin Petrov is in possession of that wide-left berth.
"I can understand that but he has a huge role to play at the club."
As Coyle is preparing to draft a number of fringe players into his starting line-up at St Mary's, Taylor is one of those in contention. Back-up goalkeeper Adam Bogdan could also make his debut, as Coyle is thinking about resting Jussi Jaaskelainen.
Danny Ward will not be involved though as the 18-year-old striker is set to go out on loan to an npower Championship club at some stage in the next fortnight.
"The likelihood is we will be letting Danny Ward go out on loan later this week so I wouldn't want to cup-tie him," confirmed Coyle.
