Rovers will run the rule over captain Grant Hanley today to see whether he'll be fit to face Bury and Morecambe in Saturday's mini tournament at the Globe Arena.
The defender missed last weekend's 1-0 win over SV Ried with a knee injury, and hasn't taken part in training so far this week.
However if Hanley comes through Friday unscathed then he should come into contention for the double header in the north of the county.
"I'm hoping that Grant will join in with the group this Friday and if there is no adverse reaction then he'll put himself in line with a chance to get some minutes on Saturday," said boss Owen Coyle.
"But having said that, we need to make sure that there's no adverse reaction given that he's had a wee bit of bother with his knee before."
Rovers also have doubts over Hope Akpan and Elliott Bennett, who picked up knocks, but Danny Guthrie is fit again after a slight groin strain sidelined him last weekend.
"Hope Akpan has a knock and has missed the last couple of days training," added the Rovers boss. "But he has such a big heart that he wants to be involved. Elliott Bennett also had a little knock in the week but trained on Wednesday.
"Danny Guthrie was ready to play against SV Ried but he tweaked his groin in the warm-up. But he played 65 minutes on Wednesday, which was great, he showed a really good attitude with that.
"So they are all moving in the right direction, we've got a terrific staff in terms of the medical team, Chris Neville and Chris Rush have worked really well with the boys in terms of the sports science side of things, so I think all in all we've got enough staff to assess them and make sure when they enter that game it is because they are able to deal with it, because we don't want to put somebody in the situation where they miss two or three weeks when it is better missing one or two days and then we go from there."
