Harvin, who has been out of practice since last Wednesday, was given a platelet-rich plasma (PRP) injection.
“He’s so itching to get back, that that’s why we sped it up,” Ryan said. “We were going to wait four days to give him the shot. We gave it to him early. Hopefully he responds on it.”
Ryan said the Bills “are shooting” for Harvin to return for Buffalo’s preseason game Aug. 29 against the Pittsburgh Steelers, but if he isn’t able to play by then, the Bills want him to play in their preseason finale, Sept. 3, in Detroit.
“He doesn’t want to go into [the regular-season opener] with no game work,” Ryan said. “He’s trying to get back on the field.”
Ryan said Sunday that he expected Harvin to return for Monday’s joint practice with the Cleveland Browns, but Harvin was not on the field for either Monday or Tuesday’s practices with Cleveland.
