Wigan Chairman David Sharpe said: “It is unfortunate that we have made this decision but with the team in such a perilous position in the league, we need to act now because we cannot afford to fall any further behind.
“Warren was appointed with the future in mind in terms of developing players but preserving our Championship status is the absolute priority and we have a duty to do whatever gives us the best chance of doing that.
“Results and performances have simply not been up to standard often enough in recent matches and although we acknowledge the difficulties faced in managing a team in a league where we are competing against clubs with much larger budgets, the nature of some of our recent defeats, especially against close rivals, has fallen short in terms of what we as a club, and all our supporters, expect.”
The club have stated that Graham Barrow will be taking over as interim manager for the rest of the season, which means Latics will not be signing a new manager until next season.
"I know what gets a Wiganer behind their team. I'll be hammering into the players what they need to give the fans.
"Game's not changed much since I played. The place to be to score is the penalty area. You won't score from halfway."
This sounds to be, Barrow is right up for it and wants to keep Wigan's Championship status.
I think Graham Barrow is the man to keep us up. Graham knows the club in and out. Barrow played for Wigan back in 1981 for five years making 179 appearances, he also managed Wigan in 1994 and has been caretaker manager for a few times since 2013.
Barrow also managed Chester (formally Chester City), Rochdale and Bury.
A lot of Wigan fans have reacted to Graham Barrow taking charge until the end of the season.
