The Ottawa Senators added some depth to their overhauled blue-line on Saturday, re-signing veteran Luke Richardson to a one-year, two-way contract.

The 39-year-old Ottawa native first signed with the Senators in August 2007. He recorded two goals, seven assists and 41 penalty minutes in 76 games during the 2007-08 campaign.

Richardson joins a revamped defence corps that lost regulars Wade Redden, Mike Commodore and Andrej Meszaros over the off-season. Filip Kuba, Alexandre Picard and Jason Smith were brought in as replacements.

The Senators also sent five players to their AHL affiliate in Binghamton, N.Y., on Saturday.

Forward Brad Isbister and defenceman Brandon Bell were the biggest names among a group that included forwards Matt Carkner, Greg Mauldin and Peter Regin.

Saturday's moves mean Ottawa now has 25 players on its roster, including three goalies, eight defencemen and 14 forwards.

The team will board a plane on Sunday and continue its training camp in Gothenburg, Sweden.

The Senators begin the regular season against last season's Stanley Cup finalist Pittsburgh Penguins in Stockholm on Saturday Oct. 4 (CBC, 2:45 p.m. ET).
