The Calgary Flames announced that center Matt Stajan is considered “week-to-week” with a deep leg contusion likely suffered during Thursday’s game against the Washington Capitals. That opens the door for Joe Colborne to make his Flames debut against the Columbus Blue Jackets on Friday.

Stajan 29 is entering the last year of a deal that nets him a $3.5 million salary cap hit (yet a cheaper $2.5 million salary in 2013-14).
