Both managers played down Chelsea defender David Luiz's bodycheck on Jack Reeves during yesterday's FA Cup clash.
Luiz apologised afterwards to Reeves, who suffered concussion in the incident.
Rosler said: "The player (Luiz) came into our dressing room, he spoke to Jake. I think that's a fantastic gesture.
"Jake Reeves is fine. He wanted to continue, but our medical staff said it's better not to. He will be okay next week."
