Jim Kelly takes battle to Western N.Y.

Hall of Fame quarterback Jim Kelly will continue his treatment for sinus cancer in western New York, according to his brother Dan.

Dan was cited in a tweet by the Buffalo Bills, the franchise Jim led to four consecutive Super Bowls in the early 1990s.

The Bills also tweeted out a quote and photo from Jim's wife, Jill Kelly.

On Thursday, Jill Kelly tweeted out that the family would be spending Easter in New York City, where Jim had been undergoing his cancer treatment.

Jim, who is fighting cancer for the second time, is also interested in buying the Bills. The franchise is up for sale after the death of owner Ralph Wilson and has drawn interest from several groups including one led by musician Jon Bon Jovi and another led by mogul Donald Trump.

"Jim will be an active participant in it moving forward," Dan, the vice president of Jim Kelly Inc., told The Associated Press last week of the Kellys' interest in purchasing the only NFL franchise for which Jim played.
