Doncaster Rovers could lose manager to Hull City and star striker to Sunderland - League One round-up
McCann, 39, led Rovers to a sixth-placed finish in League One last season before they were beaten by Charlton in the play-off semi-finals but is yet to make a decision on his future.
Sheaf, a 21-year-old defensive midfielder who can also play in defence, is highly-rated by the Gunners but could leave the London club on loan next campaign.
Meanwhile, Rovers hitman John Marquis continues to be linked with a £1million move to Sunderland, who sold Reece James to Donny yesterday.
