Paul Dickov has left his position as manager of Doncaster Rovers, the club have announced.
A statement from chairman David Blunt read: "The Board are ambitious for a top six finish and that is, and will remain our aim.
"The club will now seek applications for the post on a permanent basis. The club will not rush into making any decision, the recruitment process will be thorough and we will ensure that we appoint the strongest candidate for the position.
"From today Rob Jones will take charge of first team affairs on a temporary basis. The club has full confidence in Rob as we now look forward to a tough game against Walsall this weekend.
"The Board of Directors would like to take this opportunity to thank Paul Dickov for his efforts on and off the pitch, and wish him well for the future."
Dickov joined Rovers in May 2013, shortly after the won promotion to the Championship.
After a difficult season, Rovers looked to have done enough to secure second tier safety by March, but took just one point from their final seven games and were relegated on goal difference on the final day of the campaign.
On returning to League One, Rovers pushed for a play-off place and reached the top six, only for the form to take a dramatic dip and see them finish midtable.
So far this season Rovers have won just one league game from six.
