Nineteen-year-old Jake Forster-Caskey's 35-yard strike has given Brighton & Hove Albion a 1-0 half-time lead at Doncaster Rovers.
Doncaster were forced into a change before kickoff, as Rob Jones was injured in the warm-up and replaced by Luke McCullough.
The home side almost took a third-minute lead when Mark Duffy floated his free kick inches wide of the near post, but Brighton opened the scoring in the eighth minute when Forster-Caskey sent a thunderous 35-yard strike into the top corner.
Good chances continued to fall Doncaster's way, as David Cotterill bent an effort just wide before Yun Suk-Young was thwarted by good work from Tomasz Kuszczak.
At the other end, Stephen Ward sent a header wide of the far post when well-placed and Craig Conway forced Ross Turnbull into a good save.
