DETROIT DEFENSIVE tackle Ndamukong Suh will not be disciplined by the league for his alleged behavior during Sunday's loss against Indianapolis.

ESPN.com, citing a league source, reported that Colts players said Suh gave right tackle Winston Justice a concussion while blocking him on an interception return, and then stood over Justice and mocked him as he lay injured on the field.

No penalty was called and the league said video replay did not indicate a violation.
