Pittsburgh Pirates left-hander Steven Brault will be sidelined for at least two months after being diagnosed with a left lat strain, director of sports medicine Todd Tomczyk told reporters.

Tomczyk said Brault’s injury can heal with rest. The 28-year-old felt tightness in his left arm while pitching during Friday’s spring training game against the Baltimore Orioles.

In addition, right-hander Blake Cederlind underwent Tommy John surgery on Tuesday and will be sidelined 14 to 16 months.

The 25-year-old Cederlind made five relief appearances for Pittsburgh last season.
