After nine weeks of sitting around, Giants running back Andre Brown can’t wait to make his return Sunday. Champing at the bit, like a child on Christmas Eve, Brown said he hopes Tom Coughlin gives him the ball early and often against the Raiders — and he just may get his wish. “I just hope there are no limitations and [they let it] ride,’’ Brown said. “I hope not. This is nine weeks of sitting on my ass not doing anything.’’ Well, the months of grueling rehab weren’t exactly nothing. After coming back from a fractured fibula suffered last Nov. 25 that necessitated a protective metal plate being inserted in his leg and cost him the final five games of the season, Brown was hit in the exact same spot by New England defensive tackle Marcus Forston in this year’s preseason finale. Brown suffered another fracture, and might need to wear a specially designed carbon fiber shin guard for the rest of his career. Nevertheless, because of Brown’s dogged rehab, he’s picking that career up at 1 p.m. Sunday against the Raiders. “It’s obvious how important it is to him, and he did everything he could to get back out here, and he’s had three really good weeks of practice where he’s gotten better each day out here,’’ Coughlin said Friday. “I mean, he hasn’t played in a while. But hopefully … you always think, number one, you’ve got to take care of the ball. He hasn’t been hit and he hasn’t been tackled, so you’ve got to take care of the ball. But hopefully he’ll be able to do that.’’ Brown will get his chance right away and is expected to share the workload with Peyton Hillis.
