Millwall are being made to sweat over the fitness of key duo Lee Gregory and Shaun Hutchinson.

Both missed the away trip to Portman Road on New Year’s Day in what proved to be the club’s first away win of the season.

Gregory, arguable Millwall’s standout player this season picked up his injury in the 1-0 win over Nottingham Forest on Saturday.

“Gregs (Gregory) has a calf strain and will be out for around four weeks, which is a real blow for us,” said Millwall boss Neil Harris.

The in-form striker’s injury will rule him out of his side’s FA Cup tie with Hull, before league games against Blackburn, Middlesbrough, and Derby County.

Hutchinson late withdrawal from the travelling squad to Ipswich came via a bizarre incident at home according to Harris.

"Hutch had a real freak accident putting the bins out yesterday morning before coming to training.

"He has a deep gash on his shin, he's going to be out for a period. I don't know anymore that than at the moment so we will have to monitor him ahead of the weekend."

Millwall sit 19th in the Championship, six points the relegation zone.
