NHL bars players from altering uniforms and gear during theme nights to avoid controversy

NHL sent memo banning alterations to uniforms and gear, including Pride tape, during on-ice theme night activities.
Ban comes after some players declined to wear specialty jerseys last season, citing religious beliefs.
LGBTQ+ organizations criticized ban, saying it undermines league's commitment to inclusion.
NHL stated ban is to keep focus on games, not "distractions" from specialty uniforms.
Players can still participate voluntarily in off-ice theme night celebrations and activism.
