Sheffield United have signed Blackburn striker Nick Blackman for an undisclosed fee.

The 22-year-old has penned a two-year deal, with the option of a third, at Bramall Lane.

He becomes the sixth new arrival at the club during the summer, following Darryl Westlake, John Cofie, Matt Hill, Tony McMahon and Shaun Miller.

Blackman joined Blackburn in 2009 after starting his career as a trainee at Macclesfield.

The young forward scored 10 goals in 18 league appearances during a loan spell at Motherwell last year and has also had similar stints at Blackpool, Oldham and Aberdeen.
