Vancouver Canucks left wing Mason Raymond was unable to play in Thursday's game against the Nashville Predators because of an error in his paperwork.
The Canucks intended to re-activate Raymond, but the proper paperwork was not filed into the NHL's office by 5 p.m. ET.
"It was an oversight," Canucks assistant general manager Laurence Gilman told the Vancouver Sun. "We thought the paperwork had been filed but it hadn't, and by the time we realized it, it was five minutes too late.
"We're not happy about it. But at the end of the day, it's a mistake that forces one player to wait another couple of days to play his first game in five months. Meanwhile, we go with the same lineup that has won five straight games. There have been a lot worse mistakes in this league."
Raymond, 26, has been sidelined with a severe back injury suffered during the Stanley Cup Finals last season. He suffered a vetebrae compression fracture when he was hit by Boston Bruins defenseman Johnny Boychuk.
