Christophe Gernignon-Lecomte, director of the Meribel resort, told Radio Monte Carlo Sport: "He was shocked, a little shaken but conscious. It may be a head injury but it is not very serious."
"He was wearing a helmet and banged (his head) against a rock," the director added.
Schumacher is also one of the most popular F1 drivers ever. He retired for the second time at the end of 2012.
The German started his career with the Benetton team in 1991 and won consecutive titles with them in 1994-1995. The glorious period of his career came with Ferrari as he won five titles with the Italian outfit from 2000-2004.
His second coming in 2010 did not reap much success as he finished on the podium only once in three seasons while driving for Mercedes.
