Brady gives update on McWilliams and Mills and praises 'exceptional' Harriman
Duo were substituted in the second-half against Pompey
Joseph Mills and Shaun McWilliams were both taken off as precautions in the second-half of Saturday's 4-1 victory over Portsmouth.
McWilliams, who had another good game in midfield, was on the end of a strong challenge shortly after Ellis Harrison scored a late consolation from the penalty spot.
The 22-year-old midfielder received treatment but was unable to continue and had to be replaced by Danny Rose.
"It was straight from kick-off and the guy has gone for Shaun and kneed him in the hamstring," said Jon Brady.
"He's taken a dead leg there so we'll have to assess him. We're hoping he'll be fit because I thought he was excellent again."
Mills, who has taken the armband in Cian Bolger's absence, was substituted midway through the second-half.
Michael Harriman came on for just his second appearance under Brady but despite his limited game-time in recent weeks, Town's manager was full of praise for the experienced defender.
"I think we had to be cautious with Millsy," Brady added. "All these games are really stretching players hard.
"We had confidence in Michael to come on and do an equally good job as Millsy had done.
"Michael Harriman hasn't even been on the bench for a few of our games but that's nothing to do with him, that was just down to the balance of the bench.
"But Michael came on and was exceptional. He has worked so hard in training. He's probably one of the top three trainers every training session, even when he's not in the squad.
"With Millsy feeling a little tightness, it wasn't even a question about leaving him on. Let's get him off, look after him and get Michael on who we were confident would do just as good a job."
