yeah i think you can get in in here as hed expect you to raise his donkbet alot and the minreraise looks like hes making an infamous donkish 'feeler bet' except in reraise form not wanting to let his pair 44-99 go. I also doubt hed pot the flop with 33 here going for a checkraise on the flop or turn and if he did donk bet with it his bet would be alot smaller encouraging the raise. Therefore the only hands your worried about are jj and occasionally a slow played big pair. Also if hes donkish enough he may have called wit a raggy ace flopping a pair of 3s or gutshot and is getting feisty with them.
