TE Brad Cottam suffered what appeared to be a serious neck injury in week 14 of the 2009 season. He was thereafter placed on injured reserve and had surgery on his neck.
The Chiefs aren't confirming the move yet.
Cottam was expected to compete for time at tight end but his release (if accurate) isn't a major shock because he was behind Leonard Pope and rookie Tony Moeaki for playing time.
Cottam was a third round pick in 2008.
