The former Tottenham striker was on international duty with Republic of Ireland, playing two Euro2012 qualifiers during the week, and has returned to Los Angeles a bit tired.
Galaxy coach Bruce Arena indicated that it may be wise to rest Keane for the Home Depot Center meeting with the Rapids on Friday but did say he would reserve a decision for closer to game time.
"They looked a little tired, especially Robbie," Arena said after training on Thursday. "Robbie has had a lot of travel." "We'll just see. He'll certainly feel better [Friday] than he did [Thursday]. He seems fine. (Trinidad & Tobago international) Birchall seems fine. Birchall had less travel, probably not as demanding on him physically."
And Galaxy teammate David Beckham said Keane should be fine to play as the travel demands are just a part of a professional soccer players life.
"It's tough," Beckham said. "I did it for a few years and it is difficult. It's difficult coming back and straight into a game.
"Robbie is a professional. He'll look after himself. He'll tell the manager if he's ready to play."
