Neil Warnock is unsure how long Paddy Kenny will be sidelined
for, but expects Mikele Leigertwood to be out for at least three
weeks.
Kenny suffered a groin injury during Sheffield United's 1-0 win
over Arsenal, while Leigertwood hurt his ankle in the first
half.
Goalkeeper Kenny will definitely miss the New Year's Day game at
Middlesbrough and Warnock expects to know more come Tuesday.
"We don't know about Paddy, we will know more on Tuesday," the
Blades manager told Sky Sports News.
"He will miss Monday's game, but we will know more when he has had
a scan. At the moment it is very sore and with the swelling you can
see where the bruising is coming out.
"If you saw the tackle on Mikele you could see his ankle go and I
think it's very similar to the last time when it was three or four
weeks.
"He will have to have a scan. You can feel very sorry for him, but
that's life, it happens in football and you just have to get
on."
Phil Jagielka took Kenny's place in goal for the closing half-hour
against Arsenal and Warnock explained his philosophy behind not
having a recognised substitute keeper.
He added: "I think 95 per cent of the time I have another option
with a forward to win a game or get us a point. It is more
important to have that option.
"If I was a young manager I wouldn't dare do it - it doesn't make
sense when you've got five subs.
"Jags ain't a bad keeper and it just gives me an extra option to
win. I try to be very positive with the subs."
