A feisty clash at Ewood Park saw both teams end the game with 10 men as Rovers and Arsenal played out a stalemate.
All the action was in the second half as Charlie Gilmour saw red just after half time for the visitors before Hayden Carter also had an early bath late on in the game.
Rovers had the better of the clash, missing a number of chances through poor finishing and some good goalkeeping by visiting custodian Deyan Iliev, whilst the Gunners struggled to really test Andy Fisher.
Damien Johnson handed a start to former Premier League winner Jack Rodwell, who earned a first run out in Rovers colours since signing last month.
Fellow new boys Brad Lyons and Mitchel Candlin were available from the bench for Johnson, whilst Lewis Travis and Joe Nuttall both started having not been involved in the first team squad at the weekend.
An encouraging start from the hosts led to Willem Tomlinson forcing Deyan Iliev to beat his strike away just 12 minutes in.
Soon after, Rodwell smashed a header into the gloves of Iliev after latching onto an outswinging Stefan Mols corner.
The chances were continuing to arrive for Rovers and Joe Nuttall tested Iliev with a powerful effort from inside the box after being fed by Dan Butterworth.
Mols' near post effort flew just wide a few minutes before the break as Rovers kept up the tempo before Tolaji Bola should have been sent off when bringing Mols down on the edge of the box, before Nuttall fired the resulting free kick into the wall.
That meant both sides went in at half time all square, but Rovers could count themselves unfortunate to have not taken the lead in with them.
The visitors were dealt a blow when Gilmour was shown a straight red card for an off the ball incident involving Travis and moments later the impressive Iliev produced an excellent stop to deny Mols' header.
Mols turned provider a moment later but his cross was nodded over by Nuttall and the score remained the same.
Freddie Ljungberg's side were still dangerous on the counter attack and Robbie Burton fired just past the post after being played in down the left side.
The scores were even and so were the teams with five minutes to go as Carter was sent off for bringing down Joe Willock following a superb solo run from the Arsenal skipper.
And a moment later Rovers were thankful to Fisher to deny that man Willock with his legs after the young midfielder was played in in what was the last notable action of a lively clash as both sides earned a point for their efforts.
