Kennison, 35, played for the Chiefs for seven seasons and was their top wide receiver for most of that time. But last season, he was limited by hamstring and shoulder injuries to only eight games, catching 13 passes for 101 yards.
The 6-foot-1, 201-pound receiver played in 91 games for the Chiefs, catching 321 passes for 5,230 yards and 25 touchdowns. He had 1,000-yard receiving seasons in 2004 and 2005, joining Carlos Carson as the only players in Chiefs history to accomplish that feat.
Besides the Chiefs, Kennison has played for St. Louis, New Orleans, Chicago and Denver during his 12-year career.
