Milan: Inter Milan goalkeeper Julio Cesar was involved in a car accident on the way to training on Monday and was rested from the session, his club said in a statement.
No details were given about whether the Brazilian had been injured.
The Serie A leaders host Chelsea in their Champions League last-16 first leg on Wednesday.
I retired three years ago but I am still training with Arsenal because I have a good relation with the club and Arsene Wenger. So it's been easy to come out of retirement.
