(AP)- NHL teams made a big splash on the first day of free agency on Friday.

The Detroit Red Wings agreed to a $5.5 million, one-year contract with Ottawa Senators captain Daniel Alfredsson. Detroit also added Stephen Weiss from the Florida Panthers.

Senators general manager Bryan Murray responded by acquiring forward Bobby Ryan in a trade with Anaheim.

Less than a year after the NHL's latest lockout, many teams in the league spent big bucks on free agents despite a smaller salary cap heading into next season.

The Columbus Blue Jackets were among the big spenders, signing Nathan Horton to a $37.1 million, seven-year deal.
