Based on what you know, does it sound like we're looking at jail time?

My husband was involved in an incident in April involving another man. We were in the same circle as this other man, so we both knew him equally well. This other man had posted a comment on my(the wife) facebook page of a ual nature which was naturally offensive to my husband. I completely cut myself off from said individual, deleted him from my friends list, blocked him from my facebook, avoided him altogether. That is when he started texting my phone repeatedly. He wanted to know why I deleted him, called me every name you could think of, none of which I responded to. So my husband decided to confront the man, told him he didn't appreciate the comments or the constant texting, blah, blah, then the guy laughs in my husband's face when my husband told him to never talk to me again. At that point my husband snapped, he grabbed him, pushed him on the wall and told him how serious he was. He didn't hit the guy, but he did touch him so the guy filed a complaint against him and he is now charged with second degree ault which is a cl b misdemeanor in our state. He has NEVER been in trouble before other than a couple of minor traffic violations. We are wondering at this point, given a clean criminal record, and having never been in trouble with the law before otherwise, what are the chances of him getting sentenced to more jail time? He was stopped for a burned out tail light and was arrested Thursday evening, he was in jail for 6 1/2 hours and released on a OR. At this point we are just holding our breath, praying that he is not sentenced to more jail time. Hoping someone on here has experience with criminal law and may be familiar with the statutes on ault 2 in the state of Arkansas. Thanks so much for your help. Any information is appreciated. SN: His arraignment is at the end of Aug which we are pleading Not Guilty and at that point we will either use the public defender or hire a private attorney.
