Fabian Wilnis is the biggest doubt ahead of Sunday's match at Watford having picked up a dead leg in extra time on Thursday.
Tommy Miller remains on the sidelines with his knee problem but other than that it is pretty much a full squad which Joe Royle has to choose from.
Watford have taken Arsenal youngster Jermaine Pennant on another loan spell and he will be well known to Darren Bent and Ambrose from their days in Town's Academy sides.
Manchester United's Danny Webber has returned to Old Trafford while Sean Dyche is out with an ankle injury.
Paul Robinson is recovering from a pulled muscle and is also likely to be out but better news for the Hornets is that Marcus Gayle will return. Striker Tommy Smith is also expected to be fit.
Squad: Marshall, Pullen, McGreal, Gaardsøe, Hreidarsson, Brown, Venus, Makin, Wilnis, Clapham, Ambrose, Holland, Magilton, Wright, George, D Bent, Armstrong and Couñago.
