Middlesbrough boss Tony Mowbray could be spoiled for choice when he selects his defence for the match.
Just a few weeks ago, Mowbray was scratching around in an attempt to try to put together a back four.
But with Seb Hines fighting his way back from an ankle problem and Stephen McManus and Andrew Davies having both played for the reserves in midweek, his options have increased markedly.
Mowbray, who also expects to have Matthew Bates back on the training ground next week, told the club's official website: "It's pleasing.
"From the centre-half positions being almost empty, we are going to have some competition in the next few weeks. It's good to
see options. The more we have got, the better.
"Stephen has been out for five months, Matthew's been out for probably eight or nine weeks and then Andrew has been out for a few weeks. But they do give us some options now."
Diomansy Kamara could make his Leicester debut at The Riverside.
The Senegal striker joined Sven-Goran Eriksson's Foxes side on loan from Fulham during the international break.
He will challenge former Boro striker Yakubu, Darius Vassell and Martyn Waghorn for a starting role.
Eriksson's attacking options could be boosted further by the return to fitness of Steve Howard. The veteran is vying to make his comeback from a 10-week absence with ankle ligament damage and could be included on the bench.
Defenders Bruno Berner and Miguel Vitor, midfielder Matt Oakley and winger Lloyd Dyer are also options for Eriksson, whose Manchester City side were thrashed 8-1 by Boro on his last visit to the Riverside in May 2008.
Patrick van Aanholt (thigh) is closing in on a return but this game looks like coming too soon for the on-loan Chelsea defender.
