Farrell: No structural damage to Eduardo Rodriguez's knee

FORT MYERS, Fla. -- Boston Red Sox starting left-hander Eduardo Rodriguez was diagnosed with a subluxation of the patella tendon in his right knee on Sunday morning and will be shut down for 72 hours.

Manager John Farrell said an MRI showed no structural damage to the ligaments and tendons and that Rodriguez is walking without a brace, but added that the pitcher is bothered by swelling and is undergoing treatment.

Asked if Rodriguez’s ability to start games has been pushed back, Farrell said, “I don’t know that I can answer that right now. I think the 72 hours is going to tell us whether he’s ready to initiate putting a ball back in his hand or is there more time needed. That’s where we’re at.”

Farrell described the subluxation as being when the tendon “comes out of the groove somewhat and then slides back in, but there’s discomfort initially. The resulting fluid that built up, we’re working to get that out of there.”

Rodriguez was injured Saturday while fielding a popup in a drill with other pitchers. His spike caught in the grass and he crumpled to the turf, holding his knee. He said Saturday he initially feared his kneecap was broken.
