Justin Holbrook has admitted that it was a difficult decision to allow Aussie centre Ryan Morgan to spend 12 months on loan at London Broncos.
The St Helens boss said: "Ryan never let the team down but I couldn't guarantee him a starting spot following the arrival off Kevin Naiqama from Wests Tigers.
''It was a tough call but joining the Broncos will probably assure him of a regular place in the first team.
''He is a good and also solid player who deserved to play in Super League every week so I feel it will be beneficial for the player and ourselves. He will get a better opportunity at London.''
Morgan, who arrived at St Helens from Melbourne Storm on a three year deal at the start of 2017 and plundered 24 tries in 49 appearances, said: "It is an exciting move for me. London is an amazing city and I can't wait to get involved."
Head coach Danny Ward. the former Leeds, Castleford, Hull KR and Harlequins prop forward, said: "Ryan brings great experience to our squad on our return to Super League and I'm looking forward to watching him in a Broncos' shirt.''
Saints will be staging the Liverpool v Portsmouth FA Youth Cup tie on Tuesday, December 18.
