The Nashville Predators lost their Vezina Trophy-winning goaltender late in Friday night's win over the Calgary Flames.
Pekka Rinne left the contest early in the third period and was replaced by Juuse Saros.
Predators head coach Peter Laviolette had no update on Rinne postgame, but did say, "we didn't pull him, so something was wrong," according to the club's digital manager Thomas Willis.
Rinne appeared to collide with teammate Kevin Fiala shortly before exiting.
The 35-year-old netminder made 15 saves on 18 shots on the night. Saros stopped all nine shots he faced in the Predators' 5-3 victory.
