Liverpool could be missing two key players for Sunday's clash with Manchester United.
Martin Kelly and Raul Meireles both pulled up during defeat at West Ham United.
Kenny Dalglish said regarding Kelly: "He has pulled his hamstring and Raul got a kick in the knee. Obviously Martin is more serious than Raul.
"With a hamstring he might be struggling for next Sunday, though I wouldn't take it as a given because I wouldn't know.
"But I would have thought with a hamstring it takes a bit longer than a week. With Raul we don't know."
