DONCASTER were left to rue a crazy five–minute spell - after matching Championship side Dewsbury for the majority of an absorbing Northern Rail Cup tie.
The Rams scored three tries inside five first–half minutes, after Tony Miller’s men surged into a 12-0 lead at the Keepmoat Stadium.
Paul Hughes forced himself over between the posts and Craig Robinson’s momentum saw him ride a tackle to notch Doncaster’s second try - both goaled by Scott Spaven - to give them a deserved advantage with 12 minutes on the clock.
But Anthony England, Scott Turner and man of the match Dom Brambani scored three quickfire tries, all converted by Brambani, as the Dons’ defence temporarily parted like the Red Sea.
Dewsbury’s Luke Blake caught the home side napping with a converted try three minutes after the restart, as the Rams threatened to take a stranglehold on proceedings.
But Doncaster, whose strong running was a feature of their early play, refused to buckle and found a way back into the game when Adam Scott crossed the line on the hour mark and Spaven kicked his third conversion.
Brambani had pulled the strings all afternoon for Dewsbury, however, and the stand off’s high kick was held by Josh Tonks who touched down for a decisive fifth try.
The Dons end their Northern Rail Cup campaign at Rochdale Hornets on Sunday.
