Final answer:
If a hockey team tries to make a line change after procedure completion, the center should not be removed by the linesman for a faceoff violation unless it occurs according to the set rules of the game, which can vary by league.
Step-by-step explanation:
When a hockey team attempts to make a line change after the official line change procedure has been completed and the referee sends the players back to the bench, the linesman should not immediately remove the center for a faceoff violation. According to the rules of ice hockey, a violation during a faceoff might involve players not positioning correctly or encroaching into the faceoff circle. However, unless a faceoff violation occurs as per the set rules, the center should not be removed. It's important to check the specific league rules for any special stipulations regarding line changes, as rules can slightly differ across different leagues like the NHL, IIHF, or minor hockey leagues.
