Today the Bruins made yesterday’s report official, the Bruins and goalie Tuukka Rask have agreed to a one year, $3.5 Million deal.

After the shocking news of Tim Thomas taking the year off, the Bruins turned to back-up star Tuukka Rask. He will become a restricted free agent once again next summer. TSN in Canada was the first to break the news yesterday afternoon.

Rask’s only full season as a starter came in 2009-10 when he started in 39 games, played in 45 and lead the league with a 1.97 goals against average, and a .931 save percentage. Rask finished the season with a 22-12-5 record. Rask seemed to tire a bit in the playoffs that season as the Bruins blew a 3-0 series lead to the Philadelphia Flyers in the Eastern Conference Quarterfinals.

Rask’s season was ended short due to a leg injury last season, but he was impressive in the time he was between the pipes. Rask went 11-8 with a 2.05 goals-against average and a .929 save percentage.

Rask will join Milan Lucic, Tyler Seguin, Brad Marchand and Jordan Caron as restricted free agents (RFA) after the 2012-13 season.

The deal is absolutely a risk for both sides, and Bruins General Manger Peter Chiarelli was not afraid to admit it.

“I think it’s a risk both sides are willing to take. In an ideal world this is a deal that we look to extend come January, there are seven or eight players up [for contracts] every year and I think that’s a healthy cycle to go through” said Chiarelli. “Believe it or not, I’m trying to be cautious and I’m trying to keep the team together.”

It is now Rask’s time to shine for the Bruins after being the back-up for Thomas for years.  Let’s get ready for the 2013 season because it officially is Tuukka Time!
