The reason why Tom Lees has yet to play for Rotherham United
The Millers must wait before making a decision.
TOM Lees' time summer trial with Rotherham United has been hampered by an injury, head coach Alex Bruce has revealed.


The veteran defender linked up with the League Two Millers around a fortnight ago after rejecting the chance to stay in the division above with Peterborough United.
But a minor issue has prevented the 35-year-old from featuring in any of the friendly matches since his arrival.
In fact, he has yet to even train with the squad who are preparing for the August 8 big kick-off at home to Championship side West Bromwich Albion in the first round of the Carabao Cup.
"He's had a slight injury over the course of pre-season, so we're just monitoring that," Bruce said. "He's had a little nick in his calf.
"It's nothing major, but we've not been able to see him working with the group yet. We'll make a decision on him after he's joined the group."
The head coach hasn't ruled out the former Sheffield Wednesday and Huddersfield Town defender playing some part in the final friendly, against Derby County at AESSEAL New York Stadium next Tuesday, although that prospects seems unlikely.
"Possibly he might me involved," Bruce said.
Rotherham may allow the player to extend his trial beyond the end of pre-season and give him the chance to earn a contract with his impact in training at the club's Roundwood complex.
With 695 senior games under his belt and a good fitness record that has seen him play at least 30 matches a season throughout his long career, Lees could be a good fit for the Millers.
None of their centre-backs - Lenny Agbaire, Emmanuel Adegboyega, Hamish Douglas and Harrison Duncan - are beyond the age of 22 and his experience and leadership would strengthen the backline options.
"Maybe we could take it into the new season," Bruce said. "I need to speak to Tom."
Lees played 36 games for Peterborough last term but opted to leave because he wanted to move back north to be closer to home.
Rotherham's players have been given Thursday, Friday and Saturday off after an arduous summer schedule and will resume training on Sunday.
