The Tampa Bay Lightning claimed the rugged right-winger off waivers from the Pittsburgh Penguins on Saturday, GM Jay Feaster announced.
Roy, 31, appeared in five games with the Penguins this season. The six-foot-four, 225-pound native of Port Chester, N.Y., appeared in 104 games with the Lightning between 2002 and 2004, scoring 12 goals and amassing 260 penalty minutes.
He skated in 21 playoff games for the Lightning in 2004, recording a goal and two assists as Tampa Bay won the NHL championship. Roy signed a free-agent contract with the Penguins prior to the 2005-06 season.
"It was never our intention or our desire to lose Andre Roy in the first place," said Feaster. "However, when the new CBA was put in place, we knew that in a salary cap world we could not afford to match what some teams were going to be prepared to pay Andre and thus we lost him to unrestricted free agency.
"Having lost him, we never regained that tough, physical, gritty element that Andre brings. Now, for the first time, the new CBA has helped us in that, through re-entry waivers, we have been able to bring back a very important player to our hockey team at a salary and cap hit that make sense.
"We are thrilled to have Andre back and look forward to what he will bring to the team both on and off the ice."
To make room, centre Nick Tarnasky was assigned to the AHL's Springfield Falcons.
Tarnasky, 24, a six-foot-two, 233-pound native of Rocky Mountain House, Alta., has appeared in 22 games with the Lightning this season. He scored his first NHL goal, had an assist and served 18 penalty minutes.
