Andre Gray and Ashley Barnes featured for Burnley U23s against Sheffield Wednesday last night.
Barnes partnered Gray, who is three games into a four-match first team ban, up front in the development squad friendly at Gawthorpe.
The former Brighton striker returned from a cruciate knee ligament injury that ruled him out for 10 months in April and featured eight times in the closing weeks of the Championship season, starting once, as the Clarets secured promotion and the title.
The Lancashire Evening Telegraph says Barnes came through 45 minutes unscathed against the Owls as he begins the journey to match fitness.
