The former Three Lions striker has stated that John Stones could be an option for Roy Hodgson this summer.
Although the Manchester United man may well still make the cut, there are a number of options at centre-back that are yet to be assessed.
"The only one I might take a chance on, because we are so short in central defence, is Stones,” Lineker is quoted as saying by The Mirror.
"I really like him - he has got a lot about him. Sometimes central defenders need a little bit more experience than players in other positions because of the extra discipline and the nature of that particular role.
"But is he worth a gamble? Well, if England lose another one - if Phil Jones doesn't make it, for example - what else have we got?
“We have got Cahill and Jagielka, who have played together quite a lot, and then there is Steven Caulker, who struggles a little bit on the turn. We are short in that position."
Stones has looked assured in Roberto Martinez’s back four this season and also has the ability to play at right-back also.
The youngster’s progress has led to suggestions that Chelsea are ready to make a big-money bid for the Everton star this summer.
