Ryan Miller starts Game 5 for Canucks against Flames

VANCOUVER, British Columbia -- The Canucks have turned to veteran goalie Ryan Miller for Thursday's must-win Game 5 against the Calgary Flames.

Calgary leads the Western Conference series 3-1 and can close things out with a victory on the road.

Miller, 34, had made just one start since injuring his knee in February but stopped all 15 shots he faced after coming on in relief of Eddie Lack in Tuesday's 3-1 loss in Game 4.

"He's been in big games before, but the biggest thing is how he played in Calgary," Canucks coach Willie Desjardins said. "I thought he looked really sharp."

Lack played 25 of Vancouver's previous 27 games and helped guide the team to the playoffs in Miller's absence, but he allowed three goals on seven shots Tuesday.

"Eddie's played really great for us. He did a great job down the stretch," Desjardins said. "Miller looked good in Calgary. He was really clean the last two periods. Out of that, I think he deserves the chance."

The Canucks made another change up front, with forward Sven Baertschi slotting into the lineup.

The 22-year-old was acquired from the Flames in a trade earlier this season and was recalled from the American Hockey League before Game 4. He had two goals in three regular-season games with Vancouver.

"Whenever you're playing a former team, it's going to motivate you," Desjardins said. "He has a lot he wants to prove. He knows the guys in the other room. He just wants to show that maybe they gave up on him a little soon."

The 13th overall pick in the 2011 draft, Baertschi skated on a line with Nick Bonino and Radim Vrbata at practice Wednesday.

"It's something special for me," Baertschi said. "Being here during the playoffs is something special for any young player. Playing against your old team is something more special.

"There's no lack of motivation for sure."

Also, Canucks forward Brad Richardson returned after sitting out Tuesday. The 30-year-old missed a large chunk of the season with a nagging foot injury but played in the first three games of the series.
