Tkachuk (leg) was placed on injured reserve by the Senators, per the NHL media site. Considering Tkachuk is expected to be sidelined for at least a month, it shouldn't come as a surprise to see him land on injured reserve. Given the number of injuries the club is dealing with, a call-up from AHL Belleville ahead of Saturday's clash with Montreal seams inevitable. Rudolfs Balcers or Filip Chlapik likely top the short list of options.

Based on the paragraph above can we conclude that "Tkachuk is part of the chest"?
