OWINGS MILLS, Md. -- Two days after Baltimore Ravens linebacker Kyle Van Noy ripped the Chiefs for what he called "unprofessional" treatment of his eye injury, NFL Players Association executive director Lloyd Howell expressed disappointment in the responsiveness of the Kansas City medical staff.

Howell, who was visiting the Ravens on Thursday, said the medical treatment on-site should be provided "as quickly as possible" under the collective bargaining agreement.

"I think this was an unfortunate situation where that did not occur," Howell said. "Thank God for Kyle's situation [that] it wasn't worse. But here we are with the first game of the season; we got many more games to play. We just can't have that."

In Baltimore's 27-20 loss in Kansas City on Sept. 5, Van Noy suffered a fractured orbital bone in the third quarter while rushing Patrick Mahomes. Van Noy said Tuesday that it was "unacceptable" that it took an entire quarter for him to see the Chiefs' ophthalmologist.

The Chiefs had no comment on Van Noy's remarks.

"We've done our investigation," Howell said. "We've made the necessary parties aware of how we've got to improve, and I'm sure we will improve."

Van Noy has not practiced with the Ravens since suffering the injury.
