nighttime shooting at sports event

[Hilda1]

I have a Canon Rebel Xs and when shooting football games all is great until it gets dark.  I use the sport mode, rapid shooting and I realize there isn't enough light for the shutter speed, so blurry pictures are the result.  I use a 250 mm lens but am thinking of getting a 300 mm lens, not sure if that will improve the problem.  A friend uses a 300 mm lens (Nikon) and her photos are not blurry.  What can I do to improve the nighttime pictures?

Thank you, Hilda

While researching cameras & software for post processing you may find this discussion helpful. It's an attempt to control the noise high ISO shots produce & how to best remove it after the fact, and also compares which bodies (in the users opinion) can do a better job in camera as the photo is taken.
