MANKATO, Minn. -- For the first time on Monday, Minnesota Vikings coach Mike Zimmer will get to see safety Andrew Sendejo on the practice field.

The Vikings activated Sendejo from the physically-unable-to-perform (PUP) list on Monday, bringing him back from lower back and ankle injuries that had kept him out since the start of the team's offseason program. Sendejo started 10 games last year when injuries decimated the Vikings' secondary, but it had become apparent in recent days that he needed to get back on the field sooner than later to make an impression on Zimmer and assert himself in a crowded race for the starting safety spot opposite Harrison Smith.

It wouldn't be surprising to see the Vikings ease Sendejo back into practice for a day or two, but once he's up to full speed, it bears watching how the team will use him. Robert Blanton seemed to have the inside track on the starting spot until he strained his hamstring last Monday, and a league source said last week Blanton could miss several weeks with the injury. In his absence, Mistral Raymond has gotten some first-team work, and Jamarca Sanford has gotten a longer look after missing time with injuries of his own. Those two, plus Kurt Coleman and rookie Antone Exum, present plenty of competition for Sendejo.

The Vikings are back on the practice field on Monday afternoon, following a day off on Sunday. The team shortened its morning walk-through to special-teams work only, so Monday afternoon will be the first chance to see where Sendejo fits.
