After a fight with Kepa Arrizabalaga, the German defender was reportedly dismissed from Chelsea training on Sunday.
reported that Thomas Tuchel sent the German defender back to the dressing room five minutes before the end of the session as the pair got into a heated argument and ended up pushing each other.
The fight began when Rudiger made a late challenge on the goalkeeper during a small-sided game.
Separated by team-mates, the Blues’ boss sent Rudiger away from the pitch to calm down. The issue was resolved when Rudiger later apologized to the Spain international of his own volition.
Following a shock 5-2 defeat to West Brom on Saturday, Tuchel urged his players to stay level-headed. He told his post-match conference: "It is our first loss together. It is important to find a way to deal with it together, and that everyone knows what I feel as a part of it.
"There were some quick words to calm everybody down and to delay the talks until tomorrow because now it is too emotional, [there] is too much frustration. It is not productive."
Chelsea will next face Porto in the first leg of their Champions League quarter-final tie on Wednesday.
