Craig Levein called for players to be given more protection from Scott Brown - but could it be Heartswho need to be rein in the aggression?The Jambos are currently the joint-dirtiest side in Premiership alongside Motherwell - according to data from WyScout and Transfermarkt.
Following defeat to Celtic at Parkhead, during which Brown was involved in a clash with 16-year-old Harry Cochrane, Levein said: "I think everybody should get a little bit more protection from Scott Brown."
But Hearts and Well have committed 394 fouls each from 26 league games this season, compared to Celtic's 227.
The Celtic skipper himself has committed 32 fouls this season, the 18th-highest in the league and 13 less than Kyle Lafferty.
Levein's men have also picked up the most bookings, clocking in at 59 so far for the season and have had five dismissals, second only to Hamilton Accies with six.
These figures put Hearts rock bottom of the Premiership's fair play table, whereas Celtic top the rankings with only 227 fouls over the season.
The Hoops low foul count is likely aided by the fact they spend much more time in possession of the ball than any of their league rivals, commanding an average 66 per cent over the season.
Conversely for Hearts, their resurgence been based on solid defensive foundations and this is evident as they lead the way in defensive duels won (21 per cent) and interceptions (1290).
