The former Manchester City midfielder has been out of the first three games in pre-season due to a suspension he picked up while playing for Kevin Keegan's reserve side.
He gained rave reviews before he signed at the back end of last season and has impressed fans with his vision and hard work ethic during the summer friendlies.

Whelan was instrumental as the Ireland Under-21 team went 12 games unbeaten by beating Bulgaria 3-2 last night.
