MARTIN Olsson looks set to be out of action for at least a month after suffering a freak training ground injury on Friday.
Rovers' Swedish international missed this afternoon's draw at home to Leeds after taking a ball to the eye yesterday, with Appleton revealing he could be facing a month on the sidelines.
Colin Kazim-Richards will have a scan on Monday after limping out of this afternoon's clash with an ankle injury, with Dickson Etuhu and Lee Williamson already ruled out for the next month at least.
Rovers struggled to create too much this afternoon as they remain seven points adrift of the Championship top six.
Manager Michael Appleton, said: "I thought it was a good game to watch and a good game to be involved in, even though the scoreline didn't suggest that.
"It was two teams going toe to toe and hammer and tongs against each other and there were chances for both sides.
"It was a game both teams wanted to win but ultimately both had to settle for a draw.
"I thought we were good in possession at times and looked a threat. I thought we looked much sharper than we did in midweek."
