This appeal arises pursuant to the Texas Workers’ Compensation Act, TEX. LAB. CODE ANN. § 401.001 et seq. (1989 Act). A contested case hearing (CCH) was held on January 12, 1998, in (City), Texas, with (hearing officer) presiding as hearing officer. The record closed on January 16, 1998. The hearing officer determined that the appellant (claimant) did not sustain a compensable injury on (injury No. 2); that the alleged injury was not caused by the claimant’s wilful attempt to injure himself; and that the claimant did not have disability. The parties resolved the issue of the claimant’s average weekly wage by stipulation. The claimant appeals the findings of no compensable injury and no disability, expressing his disagreement with them. The respondent (carrier) replies that the decision is correct, supported by sufficient evidence, and should be affirmed. The finding that the claimant did not wilfully attempt to injure himself has not been appealed and has become final. Section 410.169. Only the matters timely submitted by the claimant will be considered in the resolution of this appeal. Sections 410.202 and 410.203. .
