Gianfranco Zola's side are on an impressive run, with four wins and no defeats in the last six matches.
Blackpool have become draw specialists of late, with their last three matches ending in stalemate. They go into the game in 17th place and could be drawn into a relegation scrap should they lose at Vicarage Road.
