Portguese player Filipe Morais has been signed on on non-contract forms. He is a forward, who can play on the wing or as a central striker, who made his debut in the 4-2 success over Plymouth Argyle last Saturday.
The 24-year-old joined Chelsea in 2003 and also played for Milton Keynes Franchise during a loan spell before he moved on to Millwall.
His last three years were spent in Scotland where he turned out for Hibernian, Inverness Caledonian Thistle and St Johnstone. Since leaving St Johnstone in the summer he has been a free agent.
