Reds striker Kane Hemmings is a major doubt for the club’s opening game of the season on Saturday.
Barnsley host Crawley at Oakwell in their first outing in League One after an eight-year absence.
And The Star understands striker Hemmings, one of nine new signings made by manager Danny Wilson this summer, is facing a race against time to play any part.
The former Cowdenbeath hitman has not played a single minute of competitive pre-season football in the build up to the big kick-off.
He suffered an ankle injury in pre-season training and a lack of competitive action is likely to leave Wilson with Sam Winnall and Danny Rose as his opening game strike partnership.
New goalkeeper Adam Davies is tipped to start between the posts having played more minutes in pre-season than fellow new signing Ross Turnbull.
Former Chelsea shot-stopper Turnbull played 19 minutes as a second half substitute in the Reds’ 1-1 pre-season draw with Hull City, but Davies has played the full 90 minutes in the club’s last two pre-season matches against a Manchester United select XI and Sheffield Wednesday.
Meanwhile, former Barnsley trialist Brian Jensen is looking forward to trying to help Crawley force an opening day upset.
The 39-year-old Danish keeper, who didn’t eventually end up moving to Oakwell, said: “I was on trial at Barnsley in the first year I was over in England and I enjoyed my time at the club.
“For them [Barnsley] to be favourites [to win the match] is one thing, but for them to go back straight up [to the Championship] is another.
“But anything can happen in football. It’s [League One] a tough league and they will have to work hard to do that.
“We’ll just have to see what happens, we’ll be going there confident and fancy our chances.”
