League Two club Leyton Orient have signed Millwall defender Alex Mitchell on a season-long loan deal and brought in Callum Reilly on a free transfer.

Centre-back Mitchell, 19, had a spell at Bromley last season, making 10 appearances in the National League.

Mitchell signed a new long-term contract with the Lions this month, and made his senior debut in the Carabao Cup win over Cambridge on 24 August.

Midfielder Reilly, 27, has agreed a one-year contract with the O's.

The former Birmingham, Burton, Bury and Gillingham man was released by AFC Wimbledon earlier this summer, having scored six goals in 70 outings over two seasons with the League One club.

"It's a brilliant opportunity for me," Mitchell told the Orient website.
