The Calgary Flames signed defenseman Derek year contract worth $1.55 million on Wednesday.

"Derek came to training camp this year on a two-way contract and played his way into our starting line-up," said Flames general manager Jay Feaster. "When Mark Giordano went down with his hamstring injury, Smitty stepped-up and shouldered an increased workload and did so in excellent fashion.

Smith, who is out with a high ankle sprain, has totaled two goals and 10 points in 32 games for the Flames this season.

In 43 appearances with Ottawa and Calgary over parts of the last three years, Smith has recorded 11 points.
