From your Dashboard, select "Team Management" > "Matches" > and the 3 dots " " next to the Match.
If the league has only allowed the home team to report the match info then the home team will see both the home and away team bulk stats entry options. If the league has allowed for each team to do their own minutes then each team will only see the ability to enter their own info.
You will be able to upload the game sheet under "Upload Game Sheet by selecting "choose file" and enter all the match minutes from the bulk form and it will pull from the event or match day roster.
Once all the information has been inputted click "save" at the bottom.
