Scotsman Bullen, a popular figure amongst the fans, as verbally agreed a new one-year deal to keep him at the club for the next season while injured goalkeeper David Lucas is mulling over an option to extend his deal.
Unsurprisingly, injury-prone Diallo and benchwarmer Partridge will be free to find new clubs after their one-year contracts expired but the loss of McGovern could be an unpopular one.
The former Celtic winger was the player of the season in the promotion push of 2005 but was terminally sidelined during the championship campaign - there's no doubt he will be sorely missed on and off the pitch.
Patrick Collins, who signed a one-year extension to his current deal at the start of the season just before going on loan to Swindon Town has been told he can leave the club.
Wednesday have extended the loan spell of David Graham at Huddersfield for their play-off push but it will be interesting to see the impact he makes back at S6 after being on fire for The Terriers.
Paul Sturrock will also be keen to see what happens with Wednesday's loan players - Mikkel Bischoff has not ruled out a return to Denmark when his Manchester City deal runs out in the summer while Joann Folly has been offered a new contract at Southampton despite saying he wants to stay at Hillsborough.
The Owls will be hoping to close down a season-long loan deal for Liverpool's Scott Carson too but there's no doubt that there will be plenty of competition for the England Under-21 stopper after his fine displays in blue and white recently.
