Around the league
PANTHERS: Carolina signed free agent running back Mike Tolbert to a four-year contract. Tolbert had spent all four of his seasons in the NFL with San Diego. He had 490 yards rushing and 433 yards receiving on 54 catches last season and scored 10 touchdowns while splitting time with Ryan Mathews.
CHIEFS: Kansas City signed free agent quarterback Brady Quinn and veteran right tackle Eric Winston, who was in the fourth year of a $30 million, five-year deal when he was cut by Houston to save salary cap space. Winston helped the Texans become the NFL’S second-leading rushing team.
BENGALS: Cincinnati signed free agent cornerback Jason Allen from Houston and agreed to a four-year deal with safety Reggie Nelson, who was one of their unrestricted free agents. The moves bolster a secondary that is missing top cornerback Leon Hall, who is recovering from a torn left Achilles tendon.
LIONS: Detroit re-signed punter Ben Graham to a one-year contract. Graham was the team’s punter for the final seven games of last season, putting 10 of 28 punts inside the 20-yard line with only three touchbacks.
