The central defender, signed in the summer on a free transfer following his release from Sunderland, has had to be patient since his arrival, but he finally made his full debut last Sunday against Wigan Athletic.
Kilgallon knew that he would have to bide his time to get his chance after seeing how well the partnership of Scott Dann and Grant Hanley performed last year.
But with Hanley know serving a three-match ban, the experienced defender is ready to step in.
"I came in and the gaffer said to me that Grant and Scott at the end of last season played really well and kept the team up," said the 29-year-old.
"He said he was going to start with them and it wasn't a problem I'll wait.
"But then I got injured so I was gutted with that, but I'd rather come into a team that is playing well than a team that is struggling.
"We are all good mates together and they did well, but you do get your chance in football if you wait patiently and train hard, you don't help yourself it you are moaning and sulking around the place.
"I've got my chance now, Grant is out for three games, that's football."
Kilgallon could make his first home start in Rovers' next Sky Bet
Championship match on Saturday 19th October when Charlton Athletic are the visitors to Ewood Park.
