Steve Bruce has warned players will not be fit enough to resume the Premier League on June 12 and says Project Restart should be pushed back three weeks.
Further details of Project Restart were revealed to the 20 top-flight managers during a video conference call on Wednesday last week and there remains a strong desire to finish the season.
The Premier League is working towards a rough restart date of either June 12 or June 19 with a vote due to take place on Monday to approve Phase One - a return to training potentially later this month.
