The Kansas City Chiefs have signed another inside linebacker. They inked former Dallas linebacker Orie Lemon. He played sparingly last season. He will have to earn a spot on the roster. The Chiefs recently signed inside linebackers Akeem Jordan and Zac Diles. The team has an opening at a starting inside linebacker spot. There is no guarantee any of these players will fill that spot.

In other AFC West notes:

New San Diego cornerback Derek Cox told reporters he will wear No. 22 in San Diego. He wore No. 21 in Jacksonville. Cox said he won't wear No. 21 because the Chargers will retire the number in honor of former running back LaDainian Tomlinson. The team has not announced any plans. Tomlinson left San Diego on bad terms, but he and the team have since mended fences.

The Raiders will host Chicago on Aug. 23 in their third preseason game.
