The Congolese forward brought up his dozen for the season and moved into double figures for the league campaign with an instinctive close-range header after great work from Ashley Fletcher.

Rovers were reduced to ten men when defender Derrick Williams cut down Fletcher just before the break, and Boro had numerous chances to extend our lead after the interval, Lewis Wing hitting the crossbar and Assombalonga forcing a big save from David Raya.

At the other end, Danny Graham blazed wide with a good opening and Darren Randolph got down well to save from Bradley Dack.
