AP Sources: Panthers agree to terms with OL Elflein, Erving
CHARLOTTE, N.C. (AP) — The Carolina Panthers addressed their offensive line of the first day of the NFL’s “legal tampering” period, agreeing to terms with free agent offensive linemen Pat Elflein and Cameron Erving, according to people familiar with the situation. The people spoke to The Associated Press on Monday on condition of anonymity because the deals won’t become official until the league's business year starts on Wednesday.
