On Friday, Mike Fisher of 105.3 The Fan in Dallas reported Romo opted to have a plate inserted into his collarbone. Ian Rapoport of NFL Network confirmed a plate will be screwed into his clavicle with an eye toward preventing additional breaks, via NFL.com's Marc Sessler.
However, Todd Archer of ESPN.com reported Romo will have the Mumford procedure, "in which the distal part of the clavicle is shaved down to release potential pressure against the shoulder."

What Changed for Tony Romo on Day 1 of NFL Free Agency?
The expected recovery time is six to eight weeks regardless of which procedure Romo elects to undergo, according to David Moore of SportsDay, which means the veteran signal-caller has a good chance to be ready when organized team activities begin in May.
Romo missed 12 games last season because of two collarbone breaks. Romo hadn't missed more than one game in a single season from 2011-2014 before his injury-laden 2015 campaign. He was quite productive during that time, with at least 28 touchdown passes each year.
There are major questions about Romo's durability now. However, Cowboys owner Jerry Jones is confident the 35-year-old gunslinger can lead for many years to come, per Matt Mosley of SportsDay:
What is the one unequivocal fact that you can count on relative to the preparation of this draft and on draft day is that I'm planning on [Tony] Romo being the quarterback for the next four or five years. That's a fact. You won't see a decision on draft day that will fly in the face of not believing, from our standpoint, that he'll be our quarterback for four or five years.
While expecting the four-time Pro Bowler to remain under center for the Cowboys at 40 years of age may be somewhat wishful thinking, the plate insertion could help significantly.
Dallas learned how important Romo's presence was in 2015, as it went just 1-11 without him (4-12 overall) after winning the NFC East with a 12-4 mark the previous year.
The Cowboys may have a chance to get back to that level in 2016 with a healthy Romo, which is why the success of the collarbone surgery may be Dallas' biggest key to success.
