He suffered a scary looking neck injury in the 2009 season which kept him out for all of 2010. The Chiefs briefly released him prior to the 2010 season only to re-sign him and put him on IR.
With TE Tony Moeaki currently on the PUP list, the Chiefs are a little thin at tight end.
Tight ends available right now are UDFA Charlie Gantt, Jake O'Connell and Cody Slate. GM Scott Pioli always seems to keep a healthy number of tight ends on the roster so I wouldn't be shocked to see someone else picked up.
Assuming he's not re-signed at some point, he ends his Chiefs career with 16 receptions for 183 yards and no touchdowns.
