Rovers wait on Dunn scan
David Dunn is a major doubt for Blackburn's npower Championship clash with Watford.
Dunn, 32, starred in the opening half-hour of Wednesday night's 1-0 victory over Sheffield Wednesday, setting-up up Grant Hanley's winner at the end of a fine solo run.
But his evening was cut short after the half hour and Rovers' medical staff are waiting on the results of a scan on a calf injury sustained by the playmaker.
Spanish forward Ruben Rochina could push for his first start since September's 2-1 win over Barnsley having replaced Dunn in midweek, although caretaker manager Eric Black may turn to Danny Murphy having left the club captain on the bench for the previous two matches.
Markus Olsson has returned to training following his hamstring problem but is not yet ready for first-team action.
Montenegro's Simon Vukcevic (groin) and Portugal Under-21 winger Fabio Nunes (hamstring) are set to remain on the sidelines for six to 10 days and three to four weeks respectively following injuries sustained on international duty.
