Chiefs quarterback Matt Cassel underwent surgery on his right hand late Monday. Kansas City coach Todd Haley said the procedure went "really well," and he held out hope that Cassel might return this season. Cassel suffered an injury to his throwing hand late in Sunday's 17-10 loss to the Denver Broncos. "We're just giving as much time as we can to see where he is, and as we make decisions, we're going to let you know," Haley said. "But we have not done anything with Matt yet, as far as his status."
