Matthew Adams, who has been described as a "loving and devoted dad", was assaulted at The Gough Arms in West Bromwich in the early hours of Sunday, March 19.
Detectives have launched a murder investigation as it’s believed that the injuries he sustained from the assault may have contributed to his death.
An ambulance was called to his home address in Walsall on Thursday, March 23 but the 33-year-old died on the same day.
The pub announced on its Facebook page this morning: "We have taken the decision to close the pub for the next week to enable the police to carry out their investigations without any distractions.
"It is important we can give the police our full support whilst they do this.
"If you have reservations for lunch or dinner, we are working to accommodate you at another pub nearby and we will be in touch.
"We are sorry for any inconvenience this may cause. We will be open again soon and will keep you informed here.
"Thank you for your understanding. The Gough Team."
