The Queens Park Rangers striker has delivered a frank assessment of his team-mate and skipper.
Barton, who had been booked for seven consecutive Premier League games, was sent off against Hull City on Saturday after appearing to try to hit midfielder Tom Huddlestone below the belt.
The 32-year-old's irresponsible actions left QPR in the lurch, with the west London side eventually losing 2-1 at the KC Stadium.
And forward & top scorer Austin, who did his best to give QPR a share of the points with a goal at Hull, has slammed his captain's behaviour, admitting there is only so many times Barton can say sorry.
"There’s only so many times you can say sorry," Austin told reporters.
"It’s a silly sending-off and it’s kind of cost us the game. He’s the villain and rightly so for getting sent off.
"He’s got to deal with it. He’s going to miss the next three games and he’s an important player for us, he’s our captain. We move on now."
The Hull loss leaves QPR 17th in the Premier League, although all three of the sides below the R's - and consequently in the relegation zone - failed to pick up wins at the weekend.
Burnley did, though, earn a point at Chelsea and are now level with Chris Ramsey's team on goal difference.
Next up, QPR host north London sides Arsenal and Tottenham before traveling to Crystal Palace - three important clashes during which the R's' skipper's presence would no doubt have been appreciated.
In the event, however, QPR will have to do without him - and Austin is right to be so frank in his assessment of the 32-year-old.
