James Saylor reported to the Roane County Jail on Wednesday to serve 48 hours for his guilty to plea to reckless endangerment.
Rockwood police took out a warrant for Saylor, 30, in September after a 2-year-old he was supposed to be watching was found wandering in the middle of East Evans Street.
According to court records, Saylor pleaded guilty on Dec. 12. He was fined $100.
All jail time, except for 48 hours, was suspended.
