He later played with the Denver Broncos from 2006 until 2007, the Oakland Raiders from 2008 until 2009, and was part of the Minnesota Vikings during the offseason heading into the 2010 season before he was cut prior to the start of the regular season. A few months later, Walker was suspended for four games by the league, though it’s unknown exactly what rule he violated. He finished his professional career with 267 catches for 4,011 yards and 31 receiving touchdowns. During the 2008 offseason, Walker made headlines for being the victim of an apparent robbery in Las Vegas, where he was found unconscious on the street near the Strip. Walker’s assailant was sentenced to life behind bars.
