Ex-Oregon Ducks star tight end Colt Lyerla has escaped from jail ... and now cops in Oregon have issued a warrant for his arrest.
Lyerla -- who was briefly in the NFL after he left Oregon -- was slapped with a 6 month sentence in March after being convicted on a drug possession charge.
A rep from the Washington County Community Corrections Center tells TMZ Sports they realized Colt had bolted from their facility Thursday afternoon after an open window triggered an alarm.
They searched the building and noticed he was missing.
