An expected statement by the Portland school superintendent and the president of the NAACP Portland branch about a school investigation of an incident involving the former Deering High School football coach was not issued Tuesday.

Superintendent Emmanuel Caulk said he and Rachel Talbot Ross, president of the NAACP Portland branch, planned to issue a joint statement following a meeting they had scheduled for Monday, but had not done so by late Tuesday. He said on Tuesday the statement would be made available once it was ready.

Caulk and Talbot Ross were to meet Monday to discuss issues surrounding the investigation and its aftermath.

Their disagreement over the investigation the school district conducted into complaints against football coach Matt Riddell immediately preceded his resignation from the team the day before the Thanksgiving football game against Portland High School.

The exact nature of the alleged incident isn’t clear, since none of the parties involved has described what happened or what was said.
