Chiefs' Kadarius Toney has knee surgery, hopeful to return for Week 1

Toney injured his knee during training camp while returning a punt.
He underwent arthroscopic surgery to repair a torn meniscus.
Coach Andy Reid said there's a chance Toney could play in the season opener on Sept. 7.
Toney made key contributions in the Chiefs' Super Bowl win last season.
His return would boost the Chiefs' rebuilt receiving corps.
