Sheffield United have played out a goalless first half with Mansfield Town in the first round of the League Cup at Bramall Lane.

Andy Butler missed a great chance for the Blades when he headed over from close range just after the half-hour mark.

Samuel Clucas had the visitors' best attempt moments later when his left-footed effort was well saved by Mark Howard.

Jose Baxter tried his luck from outside the box on 38 minutes, but the former Everton youngster's shot was off target.
