Court records show that Marcus Porchia was sentenced earlier this month to 15 years in prison after pleading guilty to aggravated sexual assault of a child. Another man pleaded guilty in the case in December.
Porchia's sentence will run concurrently with a 15-year term for a separate assault charge.
The 27-year-old has agreed to testify against his co-defendants, whose trials are not set.
Authorities say the girl was assaulted on at least five occasions over a three-month period in 2010 in Cleveland, about 45 miles northeast of Houston.
