Number one Westwood has been out since suffering a bruised kidney in a challenge in the second half of the game at Ipswich Town on August 15.
The Republic of Ireland custodian, outstanding in keeping 17 clean sheets last term which saw him named in the PFA Championship Team of the Year, felt a little twinge in training today - but if there is no issue, he is likely to be in the squad this weekend.
Hutchinson went off in the home game against Middlesbrough on August 29 before the international break, with captain Loovens out since limping off against Reading ten days earlier.
Head coach Carvalhal, whose side have not won in the league since the opening day of the season, said: “Kieren is good today. He felt a little thing, but we hope it is nothing special. But he is training at 100 per cent.
“If this little thing that he felt today is nothing serious or not important, he will be ready to add to the team.
“At the moment, we have a lot of solutions, which is good. And all the players, apart from Melo, are ready.
“It is more difficult for me to chose a pick and an 11. But this is good for Sheffield.”
Carvalhal confirmed the only player definitely sidelined for the weekend is Filipe Melo.
New signings Barry Bannan and Fernando Forestieri also come in the fray along with Michael Turner.
