Connacht are rumored to be signing Shayne Bolton from the Cheetahs (although I think he's not properly contracted to the Cheetahs?). Irish Qualified so would definitely fit the bill. They're also desperately in need of a loosehead so they will naturally get linked with James Cronin, but not sure if there's any weight behind that considering he could probably earn more elsewhere as its pretty unlikely he will ever be a consistent international. They'll have to make a signing here if they want to be successful next season though.
Connacht also letting another raft of players go this year:
Conor Dean - No clue
Colm de Buitlear - No clue
Cillian Gallagher - No clue
Conor Kenny - Newcastle (rumored)
Stephen Kerins - Ealing
Paddy McAllister - Retired
Quinn Roux - France, probably Toulon
Sean O'Brien - Exeter
Stephen Fitzgerald - Retired
