Middlesbrough manager Tony Mowbray admits an injury to Scott McDonald has 'intensified' the need to add striker cover at the Riverside.
The 28-year-old was withdrawn with a hamstring problem in Sunday's 3-1 win at home to Birmingham City, to put further pressure on Mowbray's squad.
"We are lookng every day, it's trying to find the right player, we have asked a few clubs," Mowbray told BBC Tees.
"The urgency of the situation now will intensify the search."
McDonald's absence leaves the Teessiders with just one first-team forward in Marvin Emnes, following Leroy Lita's departure to Swansea just before th start of the new season.
Meanwhile Mowbray has praised the debut of Belgium international Faris Haroun, who came off the bench to add the third goal Saturday's victory - their third in four league games so far this season.
"I think he likes to come from deep really, and use the energy he has got," Mowbray added.
"He's got an unusual running gait, but he covers the ground from A to B extremely fast, and when you watch him he's forever running past people to get in the box.
"Tha's why ultimately we made that change. When Scott tweaked a hamstring at half-time, we knew that Faris would get in the box probably more than Scott would.
"It paid off. He got himself a goal and ultimately the team won from a position of once again being a goal down."
