Fernando Alonso and Vitaly Petrov are each sporting minor injuries this weekend at Monza.
According to La Nueva Espana, Spaniard Alonso's injury was picked up recently as he cycled intensively between the Belgian and Italian grands prix.
"He came to Monza with a swollen knee that is now protected with a bandage," said the report.
Ferrari's Alonso told La Gazzetta dello Sport that he will keep pushing in 2011 despite being effectively out of the fight for the title.
"First place has escaped us but we can still play for second," he said. "The target has changed but not the motivation."
Renault's Petrov, meanwhile, has a sore ankle and a black eye after competing for the F1 drivers' football team at Monza's Brianteo Stadium earlier this week.

And Turun Sanomat newspaper reports that he will wear a special black helmet in qualifying and during the Italian Grand Prix to mark the Yaroslavl ice hockey tragedy.
The plane crash near the Russian city on Wednesday claimed the lives of several international players.
"I can not even express how I feel," said Petrov. "It is a terrible situation with an entire team destroyed."
