After coming off the bench for his first appearance of the season at West Ham on Saturday, a half-fit Carroll helped the Hammers to a vital three points and leapfrogged opponents Cardiff in the process.
Next up it's his former club Newcastle United in action at Upton Park on Saturday, with Collision backing the 25-year-old to build on his immediate impact.
"The big man has been working so hard to get fit, so it's great for him to be back out on the pitch and well done to him," Collison told West Ham's official website.
"Now he can build on what he did at Cardiff.
"There were a couple of dodgy touches from him, but it was a fantastic ball for the last goal and we're all happy to get him back."
