Veteran defenceman Dan McGillis has joined the Vancouver Canucks on a professional tryout.

From Yahoo! ticker,

The Vancouver Canucks on Thursday signed veteran defenseman Dan McGillis.
Terms were not disclosed. McGillis, 35, did not play in the NHL last season. The Hawkesbury, Ontario native appeared in 27 games for the New Jersey Devils during the 2005-06 campaign, recording six assists.

Just a tryout, or was he signed? Both reports came out within minutes of each other. More later.
