MONACO -- Dutchman Martijn Maaskant has replaced injured Dan Martin of Ireland in Garmin-Slipstream's Tour de France roster, the team said on Thursday.

Martin, who was supposed to help team leader Christian Vande Velde in the mountain stages, had to pull out because of tendinitis in his knee.

"Multiple team medical staff members have been working closely with Martin to resolve the issue and today team officials made the decision to replace him with Maaskant," Garmin-Slipstream said in a statement.

The Tour starts on Saturday with a 9.6-mile individual time trial in Monaco.
