Moore's agent, Lynn Lashbrook, said Thursday that Moore preferred to sign the tender rather than test the free-agent market. The move came one week after the Panthers released longtime starter Jake Delhomme.
"It's a done deal," Lasbrook told The Charlotte Observer. "He's excited about getting started for next season. He did not want to wait around. He wanted to send a message to the community and the team. I just think it's a great win-win for both parties."
Moore, 25, went 4-1 as a starter with eight touchdowns, two interceptions and a 98.5 passer rating after Delhomme was sidelined with a broken finger at the end of last season.
The Panthers placed the highest possible tender on Moore, meaning a team would have needed to surrender first- and third-round draft picks to Carolina to sign the restricted free agent.
