We're officially into the first day of Minnesota Vikings' Training Camp, and we have a move that we pretty much expected.

The team has placed Josh Robinson on the Physically Unable to Perform List. He injured a pectoral muscle towards the end of OTAs, so this move isn't a surprise.

So, what does the PUP List mean? Here's a quick refresher.

-There are two PUP Lists, one for the preseason and one for the regular season.

-If a player is placed on the preseason PUP List, they can attend team meetings, work with trainers, take advantage of medical assistance. . .everything but practice with the team. Essentially, they're rehabbing some sort of injury and not physically able to practice with the team.

-The team can remove a player from the PUP List at any time. However, when a player is removed from the PUP List, they can't be put back on it. Along those same lines, no player that actually takes the field for a Training Camp practice is eligible to be placed on the PUP List.

-If the player finishes the preseason on the PUP List, they can be moved to the regular season PUP List. If this happens, the player must sit out the team's first six games. They can still attend meetings and all of that, just like the preseason, but they still can't practice with the team.

-After the first six games, the team has a three-week window to decide whether or not the player will start practicing with the team. If the player does not practice with the team during that time, the player has to remain on the PUP List for the remainder of the season.

-If the player does start practicing with the team, the team has three weeks from the day the player starts practicing to move him to the 53-man roster. If the team does not move the player to the 53-man roster, they must remain on the PUP List for the remainder of the season.

If Robinson starts the regular season on the PUP List, he would not be able to practice with the team any earlier than 26 October, which is the day after the Vikings' sixth regular season game. Remember, it's the team's first six games, not the first six weeks, and the Vikings have the much-hated early bye week this season. (The bye for Minnesota this year comes in Week 5.)

Players like Anthony Barr, Captain Munnerlyn, and Brian Robison who missed time during OTAs with injuries were on the field this morning for the opening walkthrough. The team also placed linebacker Casey Matthews on injured reserve with a hip injury, and placed defensive tackle Shamar Stephen and wide receiver DaVaris Daniels on the non-football injury list.

That's the big personnel update for the first day of Minnesota Vikings' Training Camp. We'll have some more tidbits from what happened on Day 1 a little later on.
