Tony Mowbray insists his side will have to adjust to life in League One sooner rather than later.
Rovers came unstuck on the opening game of the season on Saturday, going down 2-1 at Roots Hall to Southend United.
The manager knows that it is far too early to be pressing the panic button, but they do have to adapt quickly to their new surroundings.
"We've had one game, we are disappointed but judge us after ten to twelve games," said Mowbray.
"I said this week in the build-up that you don't get carried away after one game.
"We have to take it on the chin, it is football, it is a long season.
"Newcastle lost their first two games at the start of last season and ended up winning the league. You have to adapt and get used to the division after a relegation, you have to adapt very quickly.
"You have to understand what it takes to win games and if this division is about winning second balls, dealing with long balls, dealing with crosses into your box, then we have to adapt to that, do that and then try and impose our football on them.
"If we learn from it then we'll get better as we move on."
Rovers are back in action this Tuesday night when they travel to take on Coventry City in the first round of the Carabao Cup.
