Charles Anton Berti Jr. (born June 21, 1972) is an American former professional football player who was an offensive lineman for four seasons with the San Diego Chargers of the National Football League (NFL). He played college football for the Colorado Buffaloes and was selected in the sixth round of the 1995 NFL draft.[1][2] Starting at guard and tackle in 1996 and 1997, Berti was an integral member of the Chargers' offensive line. A shoulder injury during training camp in 1998, put him on the IR list for most of the season. With a significant number of starters injured and limited maneuverability under the salary cap, the Chargers reluctantly traded Berti to the play-off bound Seattle Seahawks with only five weeks remaining in the season. In 1999, Berti was one of only two free-agents signed by the two-time Super Bowl champion Denver Broncos. However, another shoulder injury and subsequent surgery during training camp sidelined him again for the 1999 season. He signed with the Green Bay Packers in 2000. Days into training camp he abruptly announced his retirement.
