Coyle needs him against West Brom tomorrow as Sean Davis, Ricardo Gardner, Tyrone Mears, Gretar Steinsson, Fabrice Muamba, Stuart Holden, Chung-Yong Lee and Darren Pratley are out.
Coyle said: “Nigel came off injured which is not great. We’ll give him until the last minute. Given the heart he’s got, he’s always got a chance.
“He’s an outstanding young man, someone who puts his heart and soul into everything he does.
“He has had to play a number of times not fully fit as we’ve been decimated in that area.
“There are a lot of other players carrying knocks but all we’re concerned with is the last two games. If we win it’ll be enough to stay in the Premier League.”
