West Brom have a trio of injury concerns.
Striker Shane Long is unlikely to have recovered from the knee injury which forced him to miss the Republic of Ireland's Euro 2012 play-off success over Estonia.
Midfielder Paul Scharner is rated doubtful, also with a knee problem, while Baggies head coach Roy Hodgson will check on the fitness of striker Peter Odemwingie (ankle) before finalising his side.
Bolton boss Owen Coyle will give youngster Joe Riley his second Premier League run-out.
The 20-year-old shone on his debut in the 5-0 win over Stoke two weeks ago and will look to give a similar performance in the battle between two struggling sides at The Hawthorns.
Ricardo Gardner misses out after picking up a knock while Marcos Alonso (foot) and Dedryck Boyata (ankle) are closing in on returns but tomorrow's game comes too early. Tyrone Mears, Lee Chung-yong, Stuart Holden, Sean Davis and Sam Ricketts are long-term absentees.
