Millwall forward Mason Bennett has signed a new contract with the Championship club.

The 24-year-old scored six goals in 41 appearances for the Lions this season after joining from Derby County for an undisclosed fee last August.

Bennett also had a loan spell at The Den in the second half of 2019-20, netting twice in nine outings.

Millwall have not disclosed the length of his new deal with the club, but say it is a "long-term" contract.
