Left-back Sheehan joined Leeds from Leicester City

Leeds manager Gary McAllister has said his side's defence must improve.

McAllister was left fuming at his side's defensive display in their 4-2 Johnstone's Paint trophy defeat to League Two side Rotherham United.

"I cannot defend the defenders and their performance," McAllister told BBC Radio Leeds.

"We've only kept two clean sheets this season so we have to be better in our own box because at the other end we don't look bad."

Meanwhile Leeds fear they could be without Alan Sheehan for a significant period of time.

The left-back aggravated a hamstring injury just 10 minutes after coming on as a second-half substitute at the Don Valley Stadium.

"I think Alan will be out for quite a bit now, which isn't good news."
