Report: NFL "looking into" Seahawks possibly breaking an NFL rule

This could lead to "additional discipline" since there are multiple violations.

The NFL is looking into the Seattle Seahawks' failure to disclose an injury to star cornerback Richard Sherman during the season, per Pro Football Talk.

Head coach Pete Carroll told ESPN Radio that Sherman had an MCL injury the second half of the season. He later admitted it during a team press conference, via PFT:

"I didn't realize that we hadn't even revealed it," Carroll told reporters, via the transcript generated by the team. "I don't even remember what game it was, it was somewhere in the middle, he was fine about it, he didn't miss anything. Same with Russell [Wilson], he was fine about it. I don't know how they do that, but they did."

Per the NFL injury report rules, that's illegal:

Will the league discipline the Seahawks? Who knows. 247 Sports reported that, in 2015, the Indianapolis Colts didn't discuss the full extent of Andrew Luck's injuries, but the league decided not to take action.

On the other hand, the league fined the Jets $75,000, general manager Mike Tannenbaum $25,000 and former coach Eric Mangini $25,000 after they failed to report quarterback Brett Favre's arm injury in 2008, per PFT.

According to the report, the Seahawks have had three offseason workout violations since 2012m which resulted in the forfeiture of a full week of OTA sessions in 2017 and the loss of a 2017 fifth round draft selection. That could lead to "additional discipline" since there are multiple violations.
