Palmless or fingerless gloves
Illegal whether bought that way or modified by the player (NFHS used to allow palmless gloves manufactured that way)

Dislodged/broken goalie equipment (other than stick) or broken goalie stick
Stop play immediately (but allow shot in flight to come to conclusion). Goalie can be flagged for participating without a crosse but not for playing with a broken crosse or other missing or dislodged equipment.

Timeout after end line out of bounds
Does not change the location of the restart: the ball starts at the spot unless there was a play-on or flag-down in effect before the OOB or unless there is a dead ball foul, in which case the ball starts in the alley (NFHS used to move ball to alley in some situations). (Note: live-ball timeouts always move restart to the alley).

Regular substitution
No horn required after goal or time-serving penalty (NFHS used to require horn)

Special substitution while play is suspended for equipment violations
Now permitted under both rule sets (NFHS used to prohibit special subs in this situation)

Coach-requested equipment checks
One per team per dead ball under both rule sets (NFHS used to have no limit)

No “extra” free checks between periods or during charged timeouts (NFHS used to have no limit)

Multiple equipment violations
If a player has multiple equipment and crosse violations, NFHS 5.5 Situation C now explicitly says to penalize the most serious violation; common interpretation in NCAA is to do the same

Player pulls strings on crosse after scoring a goal
If a player pulls a string before or after the officials request to inspect the crosse, there is a 1:00 NR USC penalty and the goal is disallowed (NFHS used to only disallow for pulling strings after the official requested the crosse)

Team A is under stall warning (not in the last 2:00) with flag down; B1 gains possession
Stall warning is in effect when play resumes (NFHS used to consider B1’s possession as ending stall warning)

Stall warning in last 2:00 with score tied
Either team may be warned to “keep it in” if they are keeping the ball from play. (NFHS did not previously mention this case.)

Simultaneous technicals (or personals with total penalty time equal) with face-off pending
Face-off under both rule sets (NFHS used to award by AP)

Play suspended after a foul with ball in the attack area
Move the ball to the alley (NFHS used to move to closest point outside attack area)
