Frank Gore plans to sign with the Indianapolis Colts, a source told ESPN NFL Insider Adam Schefter. The deal is expected to be similar to the three-year, $12 million offer that the former 49ers running back received Sunday from the Eagles, according to the source. Gore's contract with Indianapolis also is expected to include $7.5 million in guaranteed money. The Colts also will host free-agent receiver Andre Johnson, who was released Monday by the Houston Texans, on Tuesday night, a source told Schefter. Gore's deal with Indianapolis would mark the end of an eventful week for the 31-year-old running back, who intended to sign with Philadelphia over the weekend before reportedly reversing his decision Monday.
