Sources: Jaguars LT Anton Harrison to undergo knee surgery

LONDON -- Jacksonville Jaguars left tackle Anton Harrison will have arthroscopic surgery on his right knee when the team returns from London next week, league sources told NFL Network's Ian Rapoport and ESPN's Jeremy Fowler.

The team does not yet know the severity of the injury, which Harrison sustained during last Sunday's 19-17 victory over Philadelphia at Tottenham Hotspur Stadium. Depending on what surgeons find, Harrison could be out three to five weeks or the remainder of the regular season.
