First team manager Neil Cox says a decision will be made on Saturday lunchtime on the team that faces Morecambe at the Sands Venue Stadium (3pm kick-off).
United host Derek Adams' side this weekend looking to make it three victories in a row following back-to-back wins on the road against Oldham Athletic and Port Vale.
Cox told iFollow Iron: "The dressing room was bubbly on Thursday morning, which was good to see and it's great that there's a team spirit.
"We got back down to work, and the boys that needed to train trained really hard while the ones who did a recovery session after playing on Tuesday did their work, as we get ready for a difficult game at home on Saturday.
"Harrison (McGahey, who returned to the side for the first time in two months on Tuesday) was aching a little on Thursday morning but we'll have a look at him on Friday, while there are a couple of other lads who have played just about every game so far this season whose bodies are a little bit tired. So we'll have a look at the situation.
"We're on a good run of form at the moment, following two clean sheets and two wins, and everyone is raring to go, wanting to start the game, which is good for me.
"Kev (van Veen) is a little bit tender and we knew he would be because we've rushed him back. It's always difficult to play three games in a week and we won't make a decision on Kev until 12noon/1pm on Saturday.
"Jordan (Clarke) is a similar situation where he hasn't played for a long time. We'll make our final decisions on Saturday after assessing how they're feeling.
"We have a lot of games to go and need to keep everybody fit."
Cox approves of the EFL's decision to allow five substitutions in a game for the rest of the season, saying: "I think it's excellent and should have been done from the beginning of the season. A lot of clubs have found it difficult as most of the players have had five or six months off, and to come back in, work really hard and play games Saturday-Tuesday every week with little rest, can be tough.
"It's the right thing to do, and a good call. It possibly helps the stronger teams in the league with bigger squads, but for me at the moment it's the right thing."
Looking ahead to the match against Morecambe this Saturday, he added: "It's all about getting results. We've defended really well away from home and counter-attacked but at home we need to be better with the ball, keep it and make more chances, while still defending as a team like we have been doing. Hopefully at home our luck can change a little bit, as we've lacked a bit of luck. There is confidence growing and let's hope it can continue.
"Morecambe have had a good start and are always tough to play against. They will come here, sit in and try to counter-attack us so we've got to be wary that we do everything properly. We will focus on what we need to do.
"Ultimately, we need to start the game off well and begin picking points up at home."
