Darius McCrary should just leave a credit card on file with the Michigan court system -- he just paid dearly again ... this time for allegedly keeping his son too long on a Spring Break trip.
A bench warrant was issued for McCrary last week after baby mama Elizabeth Alanoly filed an emergency motion claiming McCrary didn't return their kid on time.
According to court records, McCrary had to post a $15,000 bond to clear the warrant. We're told their 7-year-old son is back with Mom now.
Darius had to pay $5,500 just last month to Alanoly for back child support.
We've reached out to Darius' reps ... but no word back.
