Manchester United and Manchester City will remember those affected of the Manchester synagogue attack prior to their top-flight matches this weekend.
Yet, tributes will not be routinely held across the Premier League and EFL for Thursday's incident where two individuals lost their lives with three more wounded.
Detailed Tributes Arranged
Man Utd squad members will wear dark bands and hold a minute's silence before their match versus Sunderland at Old Trafford this Saturday, while the women's team will follow suit in their WSL fixture facing Chelsea on Friday night.
During his news conference Friday, Man Utd's head coach Ruben Amorim stated: "It is a crazy world currently, many significant events have occurred, sympathy to victims, we'll honor them tomorrow."
Man Utd's youth as well as under-21 sides will likewise don black armbands in their games.
Man City are also set to sport dark bands as they visit Brentford's ground this Sunday and have coordinated with the home team to observe a moment's silence before kick-off.
Additional Background
An observance was already planned by the Bees in memory of their head of academy goalkeeping a staff member, who died on Wednesday of bowel cancer.
The club has decided to alter the honor from a minute's applause to silence given the gravity of the recent assault.
Man City's women's team will also pay their respects before their WSL match facing Arsenal this Saturday.
Reports indicate both the Premier League and EFL are backing any club wishing to pay tribute the victims.
Past Examples
