Kansas City Chiefs veteran tight end Tony Moeaki said goodbye via his Twitter account after fracturing his shoulder against the Pittsburgh Steelers.

It's unclear if he was released or injury-waived.

"Well chiefs kingdom, it's been a pleasure," Moeaki wrote. "Best fans. Was starting to feel back to form. Bad timing for an inj."

Moeaki's timetable is unclear, but with a fractured scapula it's considered likely he would miss half the season.

Since entering the NFL in 2010, Moeaki has undergone knee operations and sustained head injuries.

Moeaki caught 47 passes for 556 yards and three touchdowns as a rookie.

Last season, Moeaki caught 33 passes for 453 yards and a touchdown.
