Sunderland boss Roy Keane has admitted to being frustrated by the slow recovery from a hamstring injury being made by winger Carlos Edwards.
The 28-year-old wideman has been sidelined for just over two months and is not expected to be back in contention for several weeks yet.
Keane told the Sunderland Echo: "We're still looking at another three weeks or so. We're doing everything we can, it's just one of those hamstring ones where it can be quite complicated.
"Carlos has seen a specialist. The positive news is that he can keep doing the recovery work that he's doing, we just to be a little more patient.
"He can do a lot of the training and if you see him walking around, he looks fine.
"But the problem comes when he twists and turns and kicks a ball and that's pretty important when you are a footballer."
Meanwhile, Black Cats skipper Dean Whitehead is content with the way his recovery from a long-term knee injury is going.
He told the club's official website: "Progress is slow, but it is progress.
"You want to push yourself as much as possible, but it's important you don't do too much and risk a setback."
