The Chicago Bears faced the Indianapolis Colts on Saturday in their third preseason game of the year.

Not only did they win, but they had some highlight plays. One of those was from a pretty unlikely source. Undrafted running back Ryan Nall broke off a massive 69-yard run, helping the Bears get out of bad field position inside their own 10.

As an undrafted rookie on a team with Tarik Cohen and and David Montgomery, Ryan Nall doesn't have the easiest route to a roster spot. The Chicago Bears might be getting their arms pulled, though.

In week one of the preseason, Nall picked up just eight rushing yards on five carries. He did have four receptions for 21 yards.

Then Nall led the team in rushing yards the next two weeks. In preseason Week 2, Nall picked up 23 rushing yards on seven carries. Nothing spectacular, but a noted improvement. He once again caught four passes for 21 yards.

Then there was this week, when he did the most with two carries. Nall led the team in rushing yards despite that low number by picking up an impressive 73 yards. As you saw, 69 of them came on that big run. This time he added one reception for 11 yards.

On that run, Nall shows good ball-carrier vision to find the hole. He then shows a nice burst of speed and a fantastic stiff arm to get the first defender off him. He drags the man that eventually makes the tackle as well for a few yards with a second stiff arm.

Barring something insane (and multiple injuries) Ryan Nall isn't going to have a major role on the Chicago Bears this year. However if he keeps playing like this, he will have a role of some kind on the team. That's something a lot of people wouldn't have guessed entering the preseason.
