When will Bennett be back

I have been looking everywhere to find out the status on MR. Bennett. At the beginning of the year they said maybee 1/2 of the year, and then they came out and said that he is progressing better than they had hoped and may return earlier, but when? I have looked on ESPN.com and all of the Vikings web sites and they don't say anything about it. Does anyone know when he is gonna be back. I think that he could be the one piece to propell us into another level. SKOL VIKES!!!!!!
