Trio missing for Sheffield United

Sheffield United will be without defender Johnny Ertl and suspended pair Darius Henderson and Lee Williamson for the derby clash with Leeds. Ertl is waiting for the results of a scan after sustaining what is feared to be a serious knee injury while playing for the reserves in midweek. Henderson and Williamson were sent off in last week's 3-0 defeat at Watford. Striker Henderson, back in the starting line-up for the first time in 11 months after a hamstring injury against former club Watford last week, was sent off for two yellow card offences. Midfielder Williamson was shown a straight red card for his aerial challenge on Lloyd Doyley and starts a four-game ban as it was his second dismissal of the season. Defender Matt Lowton has not trained this week and is doubtful due to a knock sustained in the reserves but midfielder Bjorn Helge Riise, on loan from Fulham, is back in the squad following a hamstring strain.
