But on-loan striker Martyn Waghorn has taken on the responsibility of leading the attack and the 20-year-old has scored vital goals at Rovers in the return game and in the 5-1 thrashing of Scunthorpe in the match immediately after Fryatt's injury.
Paul Gallagher has hit top form and has scored four goals in the last two home games while Lloyd Dyer has also been on the scoresheet with a crucial late equaliser at Bristol City.
"I think all the players have responded to what was a very difficult situation. Matt is a player we will miss because he has scored 12 goals for us this season and that is quite a big void for us to fill," said Pearson. "It is not always easy to fill somebody's boots but the players are working tremendously hard.
"Since Martyn has been up there he has done a very good job. I think he has taken his opportunity. Lloyd has come back into the side and has played very well and Paul is getting better and better."
