Defensive end Jared Allen, the top pass-rushing free agent left on the market, is spending Monday night eating dinner with Dallas Cowboys officials and is scheduled to continue his visit at Valley Ranch on Tuesday, according to a source. So, defensive tackle Henry Melton wasn’t the only free agent holding the Cowboys’ attention Monday night. Melton made a free agent visit to Valley Ranch on Monday and several teams, including the Cowboys, were still involved in the bidding process for the former Chicago Bears Pro Bowler late into Monday night. Melton made previous free agent visits to the Minnesota Vikings and the Seattle Seahawks. Allen’s first free agent visit came Sunday in Seattle with the Super Bowl champions. He then spent Monday in Minnesota, giving another home to an injured veteran as part of his Homes for Wounded Warriors Foundation. Allen flew from Minnesota to Dallas on Monday and is spending the evening out to dinner with club officials with the Cowboys picking up the tab. He’s scheduled to begin meetings with Cowboys coaches and executives Tuesday morning at Valley Ranch. Also, a recent national report had Allen rejecting a $30 million contract offer from Denver last week before the Broncos signed former Cowboys defensive end DeMarcus Ware to a three-year, $30 million contract. However, according to a source, that offer was never on the table for Allen to reject.
