The 0-1 EPL match between Wolverhampton and Liverpool was delayed by an injury to goalkeeper Rui Patricio.
In the 86th minute, the Portuguese collided with defender Conor Coady (who hit him on the head with his knee) and he left the field on a stretcher on 101 minutes.
The Wolves were able to release goalkeeper John Ruddy as part of testing an additional concussion replacement, despite Nuno Espírito Santo using all three substitutions.
As a result, the game resumed.
Patricio has played 9 of his 29 EPL games this season with a clean sheet.
