Tim Tebow will be introduced as the newest member of the Jets a news conference Monday. But before that happens, Tebow, because of a contract technicality, will be required to sign a rewritten contract with the Broncos on Friday and remain on Denver's salary cap for 24 hours thereafter, a source told ESPN.com's Ed Werder. That means the trade will not be official until 4 p.m. ET Saturday. Tebow flew to New York Thursday afternoon, but the contract issue forced the Jets to postpone his introductory news conference until Monday.
