Per a twitter. Henson said they scoped his knee to look at it, and they will tell him more tomorrow.

Re: Henson's Injury
 

Well if that is the case and he is ok. I want him back and Blades gone ASAP.

Henson has outplayed Blades all preseason.

O hppe tommorow brings good news for Henson. I would think he would be brought back if there was nothing more to the scope other than draining some of fluid that may built up due to swelling.
