Whatever Jacksays

Anyone know what's going on with this horse. Had a fabulous run over the Summer both over hurdles and on the level. Last I saw from trainer was that they would keep him going over the winter but hasn't been entered in anything for months. I'd hoped he would be going over for the Cheltenham Festival. I think he could have run there still as a Novice but not entered for anything today and hasn't been qualified for the Pertemps. Any information gratefully received.
