MICKEL Miller will sit out Rotherham United's EFL Trophy last-16 showdown at Crewe Alexandra as the club take no risks with his injury.
The wing-back missed Saturday's 2-1 win over Bolton Wanderers that took the Millers back to the top of League after picking up a hamstring niggle in training.
There's a chance he could be fit for tomorrow night's trip to Gresty Road but manager Paul Warne has already decided not to play him.
"He won't be involved in the Crewe game," the boss confirmed.
Miller fell victim to the muddy surfaces that affected other players as well at Rotherham's Roundwood base after heavy rain last week.
"He's just tweaked his hammy a little bit," Warne said. "It had been raining solidly for four days or so and we trained on heavy pitches.
"We had a few aches and pains. Wes (Harding) had a little bit of a groin issue. It wasn't enough to not allow him to play but he felt it in training on Thursday.
"Chieo (Ogbene) was a bit hammy sore, so he had to drop out of training. We were fortunate to get to the Bolton game with only Mickel unavailable.
"It's a thin line. You need the players to train to be ready for matches but if you train in soft conditions you cause problems."
The Millers ruled out holding sessions on astro turf, with Warne saying its hardness can lead to other injury concerns.
Miller has been pencilled in for Rotherham's FA Cup third-round tie against Championship opposition next Saturday.
"He may be available to play at QPR and if he is he'll play," said Warne.
The boss is planning to make changes to give fringe players game-time in the Crewe clash (kick-off 7pm).
