Wednesday’s penultimate pre-season game ended with a 1-0 reverse at Doncaster.
Every player in the squad got a runout at the Eco-Power Stadium in a contest that ebbed and flowed at both ends throughout.
A draw was probably the right result, although for the managers, the only thing that really mattered was extending the fitness levels of the players ahead of the new season.
Cameron Dawson’s stunning save from Tommy Rowe illuminated a first half shaded by the hosts.
Earlier, Callum Paterson was thwarted by Jack Senior on the line, after which Doncaster posed the greater threat up to the break.
Reece James executed a perfectly timed block to keep Rowe at bay and there was little incident of note thereafter in the opening 45.
Both sides refrained from commonplace mass changes at the interval and Wednesday did look livelier.
Will Vaulks drilled a low hit wide and only a brave Senior block at close quarters kept out a fierce Josh Windass volley.
But just as it seemed the Owls would strike first, Rovers stole ahead on the counter on 73 minutes.
Tyler Roberts showed quick feet and a turn of pace down the left to tee up Luke Molyneux, who planted a firm header past Dawson.
The expected changes arrived in the second half and Wednesday finished the friendly fixture with a completely different team that started.
Rio Shipston went close with a thunderous shot from just inside the penalty area and that was as close as the Owls came to a leveller.
Luton are the opponents on Saturday at Hillsborough as the summer schedule concludes before the big kick-off against Southampton.
