Philadelphia Phillies pitcher Jake Arrieta was placed on the injured list Wednesday because of an elbow injury, according to Scott Lauber of the Philadelphia Inquirer.
It is unknown whether he will choose season-ending surgery.
Arrieta has been limited this year by a bone spur in his right elbow that has been both painful and damaging to his pitching.
