FILE - In this Oct. 11, 2014, file photo, Buffalo Sabres defenseman Josh Gorges (4) and Chicago Blackhawks right wing Ben Smith (28) battle as they wait for the puck during the second period of an NHL hockey game in Chicago. The Sabres became the NHL's second team to have a goal disallowed as a result of a challenge in a 3-1 loss to Ottawa on Oct. 8. Gorges understands what the NHL is seeking to accomplish in a bid to get calls right. His only concern is whether the league might expand challenges to review other plays.(AP Photo/Nam Y. Huh, File)
