"I feel OK," Rasmus said. "I just feel like I ran into somebody. ... I'm going to try and be smart about it."
Rasmus, who has been recovering from hip surgery in October, said his right knee took a shot on the play. So his concern is overcompensating with other parts of his body for the soreness in his knee.
"I don't want to start behind the eight ball," Rasmus said. "You know, get something going in the wrong way. I want to be smart about it.
"I just didn't think it would be smart to tough it out when my body started using everything a little differently. Get my hips out of line. ... Especially in the early going coming off surgery. I want to be smart about it."
Rays manager Kevin Cash called the collision "unfortunate" adding, "Colby is a veteran player. He knows his body better than any of us. So we'll kind of let him lead the way on that. We're excited for him to get back out there and get his at-bats and get his feet on the ground playing again because we need him. He's going to make us better."
The Rays signed Rasmus to a one-year deal on Jan. 30.
