Paul Lambert believes it was important to add to Rovers' attacking options after signing Simeon Jackson on a short-term deal.
With Rovers without Nathan Delfouneso and Fode Koita absent through injury, the manager has moved to bring the Canadian international to the club.
"We needed him because of the injuries," said Lambert.
"It is a short-term thing for him and he knows that. It is up to him to prove to myself and this club that he can do it - which I think he can.
"He's got the opportunity to prove himself that he can get a longer term contract so it is entirely in his own hands, but he is hungry enough to do it.
The Rovers boss knows all about Jackson having worked with him whilst as manager of Norwich City, and hopes he can make as big an impact in a blue and white shirt as he did for the Canaries.
"He did great for us and he scored a lot of big, big goals for us as well. He's small in stature but he knows where the goal is," added the Scot.
"He offers us something different, he's a different type to Jordan and Browny and people like that. So he's a different type of player and he's got an eye for goal.
"He's been training with us for a fortnight to get himself going again, it is a big thing for him because at 28 years of age he should be hitting his prime and he's got to be hungry enough to do it and hopefully he'll make a good contribution.
"I'm still looking to bring in another striker as well."
