James Toseland admits he is uncertain as to whether he will return to World Superbike action at Monza as originally planned.

The BMW Italia rider fractured his wrist in a testing accident prior to the Donington Park round of the World Superbike Championship, the diagnosis ruling him out for at least six weeks and two events.

Certain to miss Assen as well, though it is hoped Toseland will be fit to return for the fourth round of the season at Monza, he concedes he cannot risk re-injuring the wrist if he were to fall around the high-speed Italian circuit.

"My only aim now is to try and get back for Monza, but realistically that may be a bit of a struggle," he wrote in his blog with Eurosport. "With it being my right hand I need to make sure it is fully recovered before I get back on the bike as it only takes one little tumble and I could be back to where I started.

"It's really hard because I want to be back as soon as I can but I know I cannot underestimate the time this will take to heal."

Toseland is embarking on his first season with BMW Italia in 2011, the former champion scoring two points on his debut with the manufacturer at Phillip Island.
