Another Luton substitution.

Cameron Jerome and Luke Berry come on.
An absolute corker of a strike!
10 minutes to go and Luton don't take their foot off the gas, as Alfie Doughty picks up the ball, plays a one-two, then absolutely thumps the ball in from the verge of the 18-yard line.
QPR are stunned.
QPR make a double substitution. Tyler Roberts and Olamide Shodipo come off.
Taylor Richards and Albert Adomah come on.
