The midfielder withdrew from last weekend`s game against Reading after feeling discomfort in a hamstring during the warm-up at the Madejski Stadium. The problem is not thought to be serious and McKenna hopes to get the green light to play but, with a two-week international break following this weekend`s fixtures, boss Billy Davies will not take any unnecessary risks.
Kelvin Wilson is fit to play despite suffering a broken nose against Reading, but fellow defender Chris Gunter remains unavailable as he serves the second game of a three-match ban. Striker David McGoldrick is continuing his rehabilitation after shoulder surgery and is expected to be back in contention after the international break.
