The Sharks did what they needed to do Monday to retain the rights to three restricted free agents, issuing what the NHL calls qualifying offers to Tommy Wingels, James Sheppard and Jason Demers.

General contract discussions are continuing with the three -- all 26 -- who would appear to fit into general manager Doug Wilson's stated plan for a rebuild this season.

With the timing on the eve of the NHL's annual free-agent frenzy that begins at 9 a.m. PDT Tuesday, Wilson noted again that he does not expect to be adding veterans at the same time he has asked those on his own team -- including Joe Thornton and Patrick Marleau -- to think about whether or not they want to return.

"Since we're in our rebuild mode, we're going to have some opportunity for our younger players," said Wilson, who traditionally has stayed away from any blockbuster signing on July 1.

The Sharks also issued qualifying offers to minor league defensemen Taylor Doherty and Matt Tennyson as well as goalie Harri Sateri, who will be playing in Russia next season.

  • The Montreal Canadiens have traded veteran forward Daniel Briere to the Colorado Avalanche for forward Pierre-Alexandre Parenteau and a fifth-round pick in the 2015 draft. The 36-year-old Briere, who is heading into the final year of his contract, had 13 goals and 12 assists in 69 games last season. Parenteau, 31, had 14 goals and 19 assists.

    The 49ers re-signed guard Al Netter to a one-year contract. Netter, 24, spent time on the 49ers practice squad in 2012 and '13. He also was part of the Tennessee Titans practice squad last season. He is expected to compete for a backup spot behind incumbent starters Mike Iupati and Alex Boone on the 53-man roster.

  • A person familiar with the situation says Eagles right tackle Lane Johnson faces a four-game suspension for violating the NFL's substance abuse policy. Johnson played all but one snap last season after being the fourth overall selection in the draft.

    The Ukrainian city of Lviv withdrew its bid for the 2022 Winter Olympics, becoming the third contender to drop out of the race for a games that no one seems to want. Lviv pulled out because of the continuing political and security crisis in Ukraine, where government forces are battling an insurgency by pro-Russian separatists.

    Three cities remain in contention: Almaty, Kazakhstan; Beijing; and Oslo. Lviv's withdrawal follows the earlier pullouts of Stockholm and Krakow, Poland.
