Norwich's David Bell is set to miss the start of the season with an ankle problem.
The midfielder only recently signed for the Canaries, penning a three-year deal after moving for an undisclosed fee from Luton.
Glenn Roeder confirmed that the club were aware of the problem when they made a move for the 24-year-old, but went ahead with the deal regardless to ensure that they saw off any competition for the highly-rated star.
"Bell we signed injured," the Norwich boss told the Eastern Daily Press.
"He will possibly be out for three or four weeks. We knew that when we signed him.
"We know when he's fully fit, he'll add a lot to the team.
"We knew that if we didn't sign him we could have lost him to another Championship side so we decided to move a bit quicker to be sure we secured his signature.
"But he got injured a week before he came to us in a training session at Luton. It has caused a problem with his ankle but in three or four weeks he should be back to full training. But the main thing is we've got his signature."
