Don’t expect the tight end position to be a big part of the Chiefs’ offense Sunday against the Colts. There just aren’t many options. Kansas City coach Romeo Crennel said Friday that tight end Tony Moeaki is doubtful with a head injury. With Moeaki unlikely to play against the Colts, that means the Chiefs will have just one tight end, Steve Maneri, available Sunday. Maneri, a converted offensive lineman, has five catches this season.
