Heartland goalkeeper Daniel Akpeyi and US-based striker Bright Dike have been placed on standby following the injury of Austin Ejide.
Goalkeeper Ejide suffered a muscle tear in WednesdayÔÇÖs warm-up against Cape Verde raising a major doubt over his availability for the tournament.
Ejide himself has played down his injury, saying he would be fit to return to action by the weekend, but a scan has now revealed he suffered a muscle tear that could rule him out of the AFCON.
Experts informed MTNFootball.com that a first degree tear could sideline a player for about 10 days.
“We have got result of scan on Ejide and it revealed he had a muscle tear. A statement will be made by┬áStephen Keshi┬áon him later over his availability for AFCON but two players Daniel Akpeyi and Bright Dike have been put on standby,” Eagles spokesman Ben Alaiya said.
Bright Dike of Portland Timbers in the American MLS has been a shock exclusion for the AFCON.
Ejide has not been lucky with injuries. At the 2010 Nations Cup in Angola, he was injured for most of the competition.
Officials informed MTNFootball.com that EjideÔÇÖs latest injury is a big blow for Nigeria as he has regained the No.1 shirt ahead of rival Vincent Enyeama.
He was preferred to Enyeama at the 2008 Nations Cup in Ghana by German coach Berti Vogts.
