Chelsea goalkeeper Petr Cech was reportedly involved in a physical altercation in the tunnel after his side's loss at QPR last Sunday.
Cech, who is understood to have taken a blow to the head as he left the pitch, grabbed hold of three of Neil Warnock's men in attempt to find out who struck him, according to The People.
The Czech Republic international, who wears protective headgear during games, fractured his skull in 2006 when former Reading man Stephen Hunt caught him with a trailing leg.
The incident in the tunnel went almost unnoticed in the midst of the allegations of racism and sendings off at Loftus Road.
