Marlins ace Fernandez sidelined by bicep tendon strain

ATLANTA (AP) Miami Marlins ace Jose Fernandez has a strained right bicep tendon and is likely headed for the disabled list.

Manager Dan Jennings says Fernandez had an MRI on Saturday. He says there is no timetable for his return, but he did not rule out having him back this season.

Jennings says ''We won't put him out there until we know he is 100 percent. There is no need to push it or rush it.''

Fernandez threw 76 pitches over five innings against the Braves on Friday night and complained of shoulder stiffness on Saturday. He returned to Miami and was examined by Dr. Dan Kaplan.

The 2013 NL Rookie of the Year is 4-0 with a 2.30 ERA in seven starts this year. He underwent Tommy John surgery in May 2014.
