Blackburn Rovers don't know the full extent of Scott Wharton's calf injury, which ruled him out of the defeat to Huddersfield Town.

The defender missed the 3-0 drubbing in West Yorkshire after picking up the knock against Watford. Wharton appeared to be hobbling after a challenge in the second half but finished the match, a 2-1 defeat at Ewood Park.

Jon Dahl Tomasson revealed post-match that it's a sore calf which kept Wharton out and Rovers haven't scanned him yet to determine the extent of the issue. 

The head coach also confirmed that the double change at half-time was tactical, with Andrew Moran and Sondre Tronstad replaced.

"Scott has a sore calf, we don't know how it is yet," Tomasson told The Lancashire Telegraph.

"He will be scanned one of the days when we are able to scan him. The two changes at half-time were both tactical."

Dom Hyam lasted 80 minutes in his second start since returning from a long-term ankle injury. Sam Szmodics and Harry Pickering both completed the 90 minutes despite missing the Watford match due to fatigue.
