Manchester City's James Milner is set to see a specialist on Monday as he undergoes a scan on an injured toe, which could keep him out for several weeks.
Milner, 26, picked up the injury in training last week, forcing him to miss Sunday's 1-1 draw with Arsenal, as well as Tuesday's Capital One Cup tie with Aston Villa.
City will have to wait on the results of the scan before being sure as to how long the England international will face on the sidelines, but the worst case scenario is believed to be several weeks.
"Milner has a problem in his toe. He has pain. He will see a specialist on Monday and after that we'll decide what to do," City manager Roberto Mancini said.
The former Aston Villa man has struggled to break into Mancini's first team plans, only being limited to just one Premier League start and a late substitute appearance this season, but the City manager values his versatility.
Meanwhile, right-back Maicon, who also missed the Arsenal game, will sit out the Villa clash after receiving a kick to the foot against Real Madrid in the Champions League.
