Wakefield have followed up the short-term signing of Wigan full-back Morgan Escare with the capture of Hull prop Chris Green on loan for the last month of the season.
The experienced pair will add to the depleted resources of Chris Chester's men, who have dropped into the relegation zone after winning just one of their last nine Super League matches.
Green, 29, has played almost 150 matches for Hull since making his debut in 2011 but has appeared just once, as a substitute, in the last month.
"To add a player of Chris' experience to the squad is a big boost," said Chester.
"He strengthens the pack as we enter a crucial part in the season and gives us competition in the middle.
"I'd like to thank Hull FC for allowing this deal to happen."
Green will have to wait at least a week to make his Trinity debut for the Black and Whites are Wakefield's next opponents on Sunday and he will not be able to play against his parent club as part of the loan agreement.
However, France international Escare could make his debut against Hull and will also be able to face his parent club when Wigan play Wakefield in round 27 in September.
The 27-year-old former Catalans Dragons player, who is contracted to the Warriors for 2020, has made only six appearances so far this year, the last coming three months ago.
Chester said: "Morgan will add plenty of competition across the back line and inject some energy and pace into the squad.
"It gives us a big boost as we head into the last five weeks."
Wigan executive director Kris Radlinski said: "It's obviously been a frustrating period for Morgan on a personal level, having been on the fringes of the squad this season.
"He has kept his head down and worked hard but has been unable to force his way into a team that has made week-on-week improvements and currently sits fourth in the league.
"The bottom line is, Morgan is too good a player not be featuring in the Betfred Super League on a weekly basis, so we have been working closely with Morgan's management to come to an agreement that suits all parties."
Escare said: "It has been a tough few months not playing regularly, so when the opportunity came to go on loan to Wakefield I could not refuse as all I want to do is play rugby.
"Although it will be tough not playing at Wigan, I will take this opportunity with open arms and give my best to Wakefield for the next five games to hopefully help secure their Super League status.
"I've not played much this season at Wigan and I feel fresh and ready to go for Trinity.
"Hopefully I get the chance this week to run out in front of the Trinity fans and give my all for the team."
