At the other end, Nikola Kalinic, returning from a three-match ban, did his best to give Blackburn an outlet, teeing up Martin Olsson for a long-range drive which Petr Cech saved comfortably.
The in-form Gareth Bale was again the hosts' most threatening attacking outlet, the winger forcing a smart save from Bolton keeper Jussi Jaaskelainen from range, while Roman Pavlyuchenko should have done better from one of the Welshman's crosses from six yards out early on.
