Commissioner Roger Goodell promised that he'd speak directly with Carolina Panthers quarterback Cam Newton over concerns about his on-field safety, ESPN's Ed Werder reports.

Newton was irate after receiving a low blow to the knee from Arizona Cardinals defensive lineman Calais Campbell on Sunday, stating that he'd speak to Goodell about the issue.

Panthers head coach Ron Rivera also directly spoke to Goodell on Monday, expressing concern about Newton's safety.

During the season opener, Newton suffered numerous shots to the head against the Denver Broncos, and two defenders were fined after the fact.

It appears that Newton will have data on his side.
