VIDEO: NFL explains why Quandre Diggs’ was called for holding vs. 49ers Late in the game Sunday against the San Francisco 49ers Graham Glasgow Jersey White , momentum was changing. The Lions had cut the 30-13 deficit to 30-27, and the defense was facing a third-and-2 with 2:23 left in the fourth quarter. The scene had all the makings of another signature Matthew Stafford comeback.Niners quarterback Jimmy Garoppolo dropped back to pass and threw a pass left, only to be picked off by rookie safety Tracy Walker and returned deep into San Francisco territory. A late flag negated the play and gave San Francisco an automatic first down, with Quandre Diggs called for a hold on tight end George Kittle. The call threw Lions fans into a frenzy and prompted many to blame the eventual loss on the referees. Head coach Matt Patricia submitted the play for review by the league office.NFL Senior Vice President of Officiating Al Riveron reviews these calls, and in this week’s film session he confirmed that it was the right call. “[Kittle]’s being pulled http://www.lionslockerroom.com/authentic-tracy-walker-jersey , and then he’s being wrapped on the other side,” Riveron explained. “It doesn’t matter where [Garoppolo]’s looking... as long as the quarterback has the ball, we have a foul if we have holding downfield.”Diggs’ late hold just about summed his rough day of trying to cover the bulky tight end. We’ll see if the Lions opt to put Diggs on New England Patriots tight end Rob Gronkowski Sunday night, and if so, whether Diggs fares any better in this week’s matchup. If the Rams can’t match the Lions’ offer Miles Killebrew Jersey White , the Lions will have a new backup running back."Despite hosting Spencer Ware for a visit this week, it looks like the Detroit Lions are more interested in a different free agent running back.According to ESPN’s Field Yates, the Lions have signed Rams backup Malcolm Brown to an offer sheet.So what the heck does that mean?Well, first of all, as Yates indicates Womens Jalen Reeves-Maybin Jersey , the Los Angeles Rams have an opportunity to match the Lions’ offer. Brown is a restricted free agent, and the Rams offered him an original-round tender. That gives them an opportunity to sign Brown to an identical offer and they would earn Brown’s rights.However, because Los Angeles only gave him an original-round tender (and not a first or second-round tender), if the Rams decline to match Detroit’s offer (which is unknown at the moment), the Lions will officially sign Brown and won’t have to compensate the Rams with any draft pick Theo Riddick Jersey White , because Brown went undrafted.The Lions hosted Brown for a visit last week, as we profiled on Friday. As the Rams’ backup running back last season, Brown averaged an extremely respectable 4.9 yards per carry while also contributing significantly on special teams and acting as a solid pass protector. If Detroit is awarded Brown, he would immediately come in and compete for the backup job behind Kerryon Johnson.
