Leeds boss believes attacking duo have simply not done enough to impress him.
Leeds United gained a valuable away point at the weekend, but did so without two players previously considered important to the team's mid-season success.
Six weeks on and the two are on the periphery, neither included in the squad which drew 1-1 away at Bolton on Saturday.
"They've got to liven up. They've got to do more.
"They've got to do more to get in the team. And if it means they've got to compete and work a bit harder in training, they've got to do it. Nobody's exempt."
Immediately gone were any suggestions either pair were unfit, this was an outright non-selection, a matter of preference.
They were not the only part of the side which beat Derby missing - double goalscorer that day Mirco Antenucci was on the bench and an unused substitute.
The FA Cup performance away at Sunderland appears to have been a real eye opener for Redfearn, who decided to stick with previously considered fringe players Casper Sloth and Luke Murphy.
Leeds' last Championship fixture was the return game against Derby, when they lost 2-0 and Doukara was particularly poor that day. It was realistically not a huge surprise to see him out of the team, but his failure to even make the bench was a little more so.
Adryan has been in and out of the side of late, previously suffering with his fitness, but his form had not been great either through December, and is yet to score from his attacking midfield role for the club.
Leeds have a large squad and Redfearn is right to use it and give players a fresh chance when those performing hadn't been able to stem a run of poor results.
For Adryan and Doukara however, this could be a wake up call they need in order to step up their performances.
