Marr misses Brechin return
Alloa will look to build on their two-goal advantage when Brechin visit in the Irn-Bru Scottish First Division play-off semi-final second leg without defender Jason Marr.
Marr picked up a hamstring injury in the first leg and manager Paul Hartley is warning his players their job is only half done.
Hartley said: "It's great that we're two goals ahead, but Brechin have good players and we're not through yet.
"I always said that this tie would be close and it will be, but if we work as hard we did in the first game then we'll win through.
"We'll be treating it as if the scoreline is goalless and will not be sitting in defensively.
"That would be asking for trouble and we have players that can hurt Brechin."
Brechin will add Paul McLean and on-loan St Johnstone defender Gareth Rodger to their squad.
McLean is back from suspension and Rodger is fit again, but the Glebe Park side are still without Craig Molloy, who has a knee injury, while manager Ray McKinnon has warned warning the Wasps the tie is far from over.
McKinnon said: "It's only half-time in the tie and I reckon that we can get back into things at Recreation Park.
"It's a ground we have won at already this season and while we're two goals down we're certainly not out.
"I know that we can play better than we did on Tuesday and if we do that then we'll make this second game very interesting indeed."
