The Los Angeles Angels say left-handed starter Tyler Skaggs will be out 10-12 weeks after being diagnosed with a Grade 2 right oblique strain.
Skaggs, who received a PRP injection, left Friday night's game against the Rangers with the injury.
"Tyler saw both Dr. Ron Kvitne and Dr. Steve Yoon today for a follow up appointment," the Angels said Monday in a statement. "After his imaging and clinical exam, he was diagnosed with a grade 2 right oblique strain and was administered a PRP injection. These injuries generally include a 10-12 weeks timeline before return to play."
He went on the 10-day disabled list Saturday along with first baseman C.J. Cron, who fouled a ball off the top of his foot in the eighth inning Friday night.
Skaggs, 25, is 1-1 with a 3.99 ERA in five starts this season. He had Tommy John surgery in 2014.
The Angels are already withoutGarrett Richards, another member of the starting rotation. Richards is on the 60-day disabled list after he was diagnosed with a strained right biceps earlier this month.
