Todd Heap, a long-time tight end with the Ravens, has signed on to play for the Cardinals. Heap was born and raised in Arizona and played his college ball at Arizona State. The Ravens released Heap last week and he's drawn interest from several teams, including the Jets.

The Colts have re-signed running back Joseph Addai, a team source said. Addai led the Colts in rushing four consecutive seasons until last season when injuries helped to hold him to 495 yards.

The Bears have signed former Cowboys running back Marion Barber to a two-year contract.

The Rams have signed wide receiver Mike Sims-Walker to a one-year contract. Sims-Walker had 43 catches with a 13.1-yard average and seven touchdowns last year for the Jaguars.

The Colts have signed former Texans backup quarterback Dan Orlovsky. Houston released Orlovsky when they agreed to terms with Matt Leinart to serve as the No. 2 quarterback behind Matt Schaub. "I'm just waiting to get my travel information from Indy," Orlovsky said. "Once I get that I'll head to the airport. "I'm excited about it, for sure. I'm excited about the challenge of going up there and learning about a pretty complex and new offense and having the opportunity to go learn and compete and be a part of a good football team and a good organization."

Vincent Jackson signed his $11 million franchise tender with the Chargers on Friday afternoon. Jackson missed last year's training camp and most of the season because of a salary dispute. However, he said there isn't bad blood between him and the team. "When I came in this afternoon, it was like a reunion with your family," Jackson said in his first public comments since January. "Guys welcomed me with open arms." During the lockout, Jackson was one of 10 named plaintiffs in the antitrust lawsuit filed against team owners. He said it was "kind of a shock" to learn of media accounts that depicted him as a lead plaintiff who could hold up the next labor pact. "I'm not sure where that came from," Jackson said. "There was just a group of plaintiffs in the lawsuit, and I was one of many plaintiffs, and we were all in the pursuit of the same thing."

The Dolphins have re-signed defensive lineman Tony McDaniel and added free-agent linebacker Jason Trusnik. Miami has also agreed to terms with veteran linebacker Kevin Burnett, who will replace Channing Crowder, according to a source.

The Jets re-signed safety Eric Smith to a three-year contract late Friday night, a league source confirmed. Smith and Brodney Pool, also a free agent, shared the job opposite Jim Leonhard last season, with Smith starting six games and three in the playoffs.

The Giants have signed Boston College linebacker and cancer survivor Mark Herzlich, who many consider the jewel of the undrafted rookie class. "It is a great opportunity for me to get in and play and be on a team," Herzlich said. "And it is a great community feel, it is a family-owned team. I know the Maras and (coach Tom) Coughlin from Boston College. It seemed like a great place to be."

As the longtime offensive architect of the Colts, Tom Moore had many memorable battles with Rex Ryan, who ran the Ravens' defense before taking over as head coach of the Jets in 2009. Now after years of competing against him, Ryan has hired Moore as a consultant for the Jets, the New York Post reported Thursday.
