Brewers complete double swoop
Burton have bolstered their attacking options by signing Leyton Orient striker Michael Symes and Burnley forward Alex McDonald.
Symes has moved to the Pirelli Stadium until the end of the season, while McDonald has joined the League Two promotion chasers on an initial month-long deal.
Symes joined Orient from Bournemouth in the summer, scoring twice in 18 appearances for Russell Slade's side.
McDonald featured twice for the Clarets in August before spending the majority of the first half of the campaign on loan at Plymouth, playing against Burton in November.
