Below is this week's segment – Coaching Box Expansion - Listen

There’s one very visible change coming to the basketball court this year in Michigan. The sideline coaching box has been expanded from 14 feet to 28 feet. The expansion was allowed by national playing rules for individual state association adoption a year ago, but the change was announced too late for Michigan to opt for the larger box.

Even though the box size has changed, other rules for behavior inside the box have not. Only the head coach is allowed to stand up in the box as allowed by rule; once the coaching box is lost due to a technical foul, there is no way to get the coaching box back; and all other related rules restrictions apply.

The change brings the game in Michigan full circle from when the old “seat belt” rule was created in the 1980s. Hopefully, common sense will prevail, and the coaching box will be used for just that – coaching.

Be the Referee: Field Hockey Substitution

Below is this week's segment – Field Hockey Substitution - Listen

We are on the pitch today for a field hockey “You Make the Call.”

During the execution of a penalty corner, the defending goalkeeper is struck on the hand and cannot continue. How is play resumed?

  • Allow a properly equipped goalkeeper to substitute.
  • Disallow any substitution; the injured goalkeeper must remain in the game.
  • The defending team shall forfeit.

If you said to allow the substitution, you are correct. Under Rule 4-4-3, a goalkeeper substitution is permitted during a penalty corner in the event of injury or suspension. Once the new goalkeeper is ready, resume play with the continuation of the penalty corner.

Field players, however, may not substitute until the penalty corner has been completed. This ensures proper game flow while prioritizing player safety.
