Although we find the employer/carrier (e/c) received proper notice, we find that the JCC erred in holding the second e/c solely responsible for coverage of the claimant’s present condition. Because no competent substantial evidence supports the JCC’s finding and because all testimony indicates the injury resulted from an aggravation of a preexisting injury, we reverse and remand for further proceedings consistent with this opinion. See Oaks Farm v. Berry, 500 So.2d 175 (Fla. 1st DCA 1986).
