Would definitely need a replacement if true, I liked Sharp's work rate & wish him well whatever happens.
As a side note, last week bomber said we couldn't bring in anyone else till Obst had gone. However only 2 or 3 weeks ago he also said that we had just missed out on an Aussie who decided to stay in the NRL.
So surely we must have space on the cap regardless of what Obst does unless the Aussie was coming for nowt!
