Huddersfield have agreed to allow threequarter Luke George to continue his loan spell at Hull KR.
George has played the last three Super League matches for Rovers, scoring his first tries for them in Sunday's 44-18 win over Wakefield, which brought to an end his initial loan spell.
"We're going to go week by week for now," said Giants coach Paul Anderson.
George will play in Saturday's Hull derby at the Magic Weekend but can be recalled by his parent club at a week's notice.
Meanwhile, Anderson has confirmed that second rower Jacob Fairbank, who is on loan to Bradford, is free to play against the Giants at the Etihad Stadium on Sunday.
Some clubs include a clause in loan agreements preventing players lining up against their parent club but Anderson is happy for his players to face Fairbank.
"We're fairly healthy and it seemed a no-brainer to let Bobby go play Super League," he said.
You've got to look at what's best for the player as well. One of the reasons he has gone to Bradford is to play Super League and to stop him doing that because they're playing us is the wrong thing to do.
"When I spoke to Bobby to tell him Bradford wanted him on loan I said one of the conditions was that they wanted him to play against us.
"He said 'yes, no worries'. If he'd have said 'I'm not so sure' then we probably wouldn't have done it."
