Harbaugh declined to pour any more verbal gasoline on the Ravens' fiery disagreement with the replacement referees, who nullified Jacoby Jones' touchdown catch on an offensive pass interference call. "We do have confidence in the league in the way they approach the officials, both in the short term and the long term, so we'll trust them to take care of that," Harbaugh said when asked about the labor dispute between the league and the regular officials. "We'll focus on our jobs in getting our teams ready." As for the Ravens' complaints, Harbaugh opted to not pile on further after calling the game chaotic on Sunday: "As far as the officiating goes, I'm not going to have any comment about it because it all goes hand in hand. I'm not going to have any comment about it whatsoever in any way, shape or form." ... Harbaugh praised rookie kicker Justin Tucker, who connected on field goals from 56, 51 and 48 yards. "He did a great job, but next week is a new week so we'll hold his feet to the fire," Harbaugh said. "The thing I like about 'Tuck' is he's workmanlike. He really pays attention to detail, technique. It's never too big for him, so he's off to a good start." ... The Patriots signed former Ravens rookie safety Cyhl Quarles to the practice squad recently. Will Bill Belichick glean any insight from Quarles' Baltimore background, or the Ravens from former Patriots safety James Ihedigbo? "They signed a guy, Cyhl Quarles, so I'm sure he's being put under the bright lights right now being interrogated," Harbaugh said with a laugh. "There's always value to that, sure."
