Oft-injured Chiefs tight end Tony Moeaki’s career has suffered another setback.

Chiefs coach Andy Reid said Moeaki suffered a shoulder fracture in last Saturday night’s overtime win at Pittsburgh. It is uncertain how long he will be out.

Moeaki a four-year veteran had a history of injuries in college at Iowa and it has followed him with the Chiefs. He missed all of the 2011 season with a knee injury sustained in the final pre-season game and he missed all of the off-season program this year after undergoing a procedure on his knee.

Moeaki who caught 47 passes for 556 yards and three touchdowns in 15 games as a rookie also played in 15 games last season and caught 33 passes for 453 yards and a touchdown. He missed one game 2010 and 2012 due to a head injury.
