Major League Baseball plans to eliminate home plate collisions, possibly as soon as next season but no later than by 2015.

New York Mets general manager Sandy Alderson, chairman of the rules committee, made the announcement Wednesday at the winter meetings in Lake Buena Vista, Fla.

"This is, I think, in response to a few issues that have arisen," Alderson said. "One is just the general occurrence of injuries from these incidents at home plate that affect players, both runners and catchers. And also kind of the general concern about concussions that exists not only in baseball but throughout professional sports and amateur sports today. It's an emerging issue, and one that we in baseball have to address, as well as other sports."

Alderson said wording of the rules change will be presented to owners for approval at the Jan. 16 meeting in Paradise Valley, Ariz.
