A player at Mexican club Monterrey was reportedly hospitalised and required ten stitches after clashing with his manager, who is a former Manchester City cult hero.
As reported by Marca, there is now uncertainty over whether the player will be able to feature against Guadalajara on Sunday.
The player is said to have suffered a badly cut leg.
Monterrey, who are in ninth place in the table, have won just one of their last five games.
The player is reported to have kicked a glass door following an argument with his manager.
However, the manager has denied that there was a conflict.

The player in question is Sergio Canales, the former Spain international who previously played for Real Madrid.
Canales, 34, is said to have been involved in a heated exchange with manager Martin Demichelis.
Demichelis explained to the media that he is willing to discuss his philosophy with his players, while he denied a conflict with Canales.
When leaving training, Demichelis told the press: ‘Put whatever title you want. In every sport, in every locker room, there are always these exchanges of opinions.
‘I’m not authoritarian; I like to listen and hear the player’s opinion so I can draw the best conclusions.
‘We know what’s at stake this weekend, and we want to represent the club as it deserves. I have no doubt that whoever goes out to play this weekend will be a true warrior, and that’s the most important thing.’
Demichelis was appointed as Monterrey boss in August last year, having previously been in charge of River Plate.
During his playing career he made 51 appearances for Argentina and featured prominently for Bayern Munich.

Between 2013 and 2016 Demichelis played 106 times for Manchester City. He won the Premier League title in the 2013-14 campaign and also won the League Cup twice.
Canales made 15 appearances for Real Madrid after joining in 2010 and later played for clubs including Valencia, Real Sociedad and Real Betis.
