The Notre Dame product is a strong pass-catcher. He missed all of last season with a shoulder injury, but Carlson, 6-foot-5, 251 pounds, has put up some good numbers when healthy.
He has 137 receptions for 1,519 yards and 12 touchdowns in three season. He would pair with Tony Moeaki, who was outstanding as a rookie in 2010, but he missed all of last season with a knee injury.
So, if the Chiefs sign Carlson, they will have two talented tight ends looking to rebound from injury.
