Falcao participates during Colombia's training session

Radamel Falcao was seen participating in a light training session Monday with his Colombian teammates as he works towards match fitness for June's World Cup in Brazil.

The Monaco striker suffered a ruptured cruciate ligament in January and Colombian manager Jose Pekerman says he will avoid naming the official 23-man roster until he's certain whether or not Falcao is able to participate.

"I'll wait until the last day, until the last hour, the last minute, to give out my list of 23," Pekerman said, via the Daily Mail.

Ever since injuring his knee, Falcao's been adamant about his ability to return from such a serious injury, despite the fact England's Theo Walcott suffered a similar injury three weeks before and was ruled out of the competition almost immediately after the injury occurred.

Time is running out, as the deadline to submit final rosters for the tournament is June 2.
