LINK ALAMEDA, California (Ticker) - Oakland Raiders owner Al Davis has said that firing Art Shell after the 1994 season was a move he always regretted. Now he is trying to rectify that mistake. The Raiders on Friday hired Shell as their coach for a second time. He will be introduced at a news conference on Saturday. Shell became the NFL's first black coach of the modern era when he was hired by Davis during the 1989 season and compiled a 54-38 record with the Raiders, including a trip to the AFC championship game in January 1991. Despite the winning record, Shell was not hired by another team after being fired by the Raiders. Shell, a Hall of Fame player as a tackle with the Raiders and a member of two Super Bowl-winning teams, had been working as the senior vice president of football operations and development for the NFL. The Raiders waited until after the Super Bowl to interview Pittsburgh Steelers offensive coordinator Ken Whisenhunt for the coaching position. But Whisenhunt decided to stay with Pittsburgh and Davis turned to Shell.
