Tony Mowbray has revealed that Craig Conway could miss the start of the 2017-18 season.
The popular Scot was absent for the pre-season wins over York City, Morecambe and Grimsby Town with a hamstring strain, and the Rovers boss feels the start of the new campaign could come too soon for the midfielder.
"Craig will probably miss the start of the season, another couple of weeks and then he will have to come back and start training.
"It's just a hamstring problem, it's not a long-term thing, just another week or so."
But there is better news over Corry Evans and Darragh Lenihan.
The duo missed the victory at Blundell Park, but the manager hopes both could return for Friday's friendly at Carlisle United.
"Darragh has a knock on the outside of his knee which is a bit sore but that shouldn't be too much of an issue – he has a chance for Friday," added Mowbray.
"Corry should be all right for Friday, another two or three days, he just had a knock to his ankle in a tackle in the last game."
Tickets for Friday's match at Carlisle are currently on sale. Details on pricing and availability can be found here.
