Colin Calderwood's patched-up troops are seeking to break a run of two defeats in a row and his team may be bolstered by Oyvind Leonhardsen playing some part in the game after suffering a calf injury.
The injury kept Leo out of Norway's trip to Tunisia on Wednesday and Steffen Iversen also remained in London.
"I think Gary Doherty is going to play along with Stephen Clemence," reported Colin on Monday. "In the morning we're going to check on Leo, we'll see how he feels and if he wants to do half a game or something like that, he's only had two training sessions.
"The rest of the team will be as normal - George Snee, John Jackson and James Quilter will play. Similar to what is was last week."
Colin also reports that Chris Armstrong is not quite ready for a reserve outing.
"Chris is hopefully pencilled in for next week or part of it against Chelsea. He's not ready to join in yet, he's got a schedule to get through with Kunle (fitness coach) and a bit more getting back used to training with the ball and the group.
"He needs to feel alright in doing that on successive days up to five in a row. He's doing okay though, fine."
Colin adds that to succeed over Watford basic mistakes from the last game will have to be eliminated.
"The performance against Charlton was good, and if you look at the video of the Arsenal game some of it was good. Real basic mistakes, not errors because they didn't know they were doing them, gave Arsenal a real control of the last third of the pitch.
"If we can stop those sort of problems at Watford, if they arise again, then we'll do alright. For 25 minutes we were okay, but Arsenal then built a bit of pressure on us and had a rythm and tempo to their play that we didn't.
"I think they will be a young side very similar to us. We'll probably end up with some of the under-17s playing towards the end of the game so that could be good for us. Mark Yeates and Danny Foster are definitely coming.
"It's a definite benefit the earlier you get them into that environment."
Gary Doherty and Stephen Clemence will continue along the comeback trail for the reserves against Watford tonight at Vicarage Road, kick-off 7pm.
